Long overdue updates

With the release of Joomla 3.4 it was decided that we really should update our website.  Then we have the PHP update required since 7.4 is now out of support.

So we took a demo website and using PHP 8.0 and fixing numerous PHP errors relatng to the ordering of required paramters needing to come before options ones, and also the use of {} braces now not permitted we managed to get the site up, but the front page etc still require some major work.

Our second backup site was much easier and looks reasonable althought more work is require.

Our main site was a bigger headache. On changing to PHP 8.04 we ended up with a blank page for front end and admin area.   Cannot go back to PHP 7.4 and cannot get into the site so have to resort to using configuring PHP initialisation files.

For Joomla debugging after blank screens and this even works if the Joomla admin password is unknown.

To adjust error_reporting, we open configuration.php and add

public $error_reporting = 'maximum';

2. Additionally, we turn ON full error reporting in PHP by adding these to the php.ini file.

display_errors = On
error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT

3. Now, Joomla errors will be accessible from the error log file.

To be logical we shall first concentrate upon fixing the errors introduced by the change from PHP 7.4 to PHP 8.0. Then we will look into changing to PHP 8.1 and possily later to PHP 8.2. Then we will look at the Joomla 4 templates especially since out site template in Bootstrap 3 which is virtually impossible to Bootstrap 5. The admin template is also going to require some work.

Errors seem to fall into certain types:

a) Use of {} braces around a vaue that should be [] instead.

b) Array variable passed to a function, so add (array) in front of offending parameter.

To be continued.




IP Mapping and Google Maps

We have recently been notified of a problem where the Maps generated by our IP Mapping using the Google Maps API were never completing.

Viewing the Java console log we could see that there were reported problems as follows:

Blocked loading mixed active content ""[Learn More]">ip-maps-and-visitors
JQMIGRATE: Migrate is installed, version 1.4.1">jquery-migrate.min.js:2:542
Blocked loading mixed active content ""[Learn More] https://www.zzzzzzzz/ip-maps-and-visitors">ip-maps-and-visitors
Loading failed for the <script> with source “”.">ip-maps-and-visitors:61:1
 ReferenceError: google is not defined[Learn More]">ip-maps-and-visitors:94:11
Where xxxxxxxx is the specified API key, and zzzzzzzz is the web site which reported the problem, which we have masked for security problems.
This seemed to be a situation of a site using https yet the code still using http for the internal addresses, and further investigation revealed that this was indeed the case.

However in looking further we discovered a few further interesting aspects of the use of the Maps API which are worthy of mentioning.

The first is that in line with many cloud computing providers, the Google Maps API moved to a pay-as-you-go pricing structure on 11th June 2018.

The newly-named Google Maps Platform was brought under the Google Cloud umbrella and consists of three core products: Maps (for delivering customised dynamic maps, Street Views and 360° views), Routes (directions and traffic) and Places (location names, addresses, reviews etc). Each has its own pricing structure.

More importantly the new pricing strategy employed by Google for their Maps Platform is a freemium one – all users get to make $200-worth of API calls for free each month.  Thjs means that one has to use an API Key and register a billing account, even if you never are going to pay.  Even if your usage falls well within the free $200 credit, you still have to create an account and provide Google with billing details to keep using the APIs.  It should be possible to set up a usage cap, but we have been unable to do this yet, until the 'free' time expires.

It is also important to add some restriction on the API key to secure it. We found this web page How to Fix “This page didn’t load Google Maps correctly” Error.

This proved very useful in setting up an API Key, although we did encounter some problems setting up the HTTP referrers, in getting them to 'take'.

The fix involved us modifying the code in two php files located in the Jooma/modules/mod_ipmapping_mapper directory. These files named 'mod_ipmapping_mapper.php' and 'minify_js.php', were modified to change the internal http prefix to https and this resolved the coding problem.   The latter file is probably the more important to change. The official fix will be included in the next schedued release.

Joomla 3.9 released


 Joomla 3.9, The Privacy Tool Suite

The Joomla! Project is proud to announce the release of Joomla! 3.9, the latest in the ‘Joomla! 3’ series.

This new release packs in more than 250 improvements for the Joomla CMS – central to which is a full privacy tool suite, which will make site compliance faster and simpler (not to mention the lives of developers a whole lot easier)!

What’s new in Joomla 3.9?

Here are just some of the new features …

The Privacy Tool Suite by Joomla

  • User Consents - Make light work of data privacy requirements
    Need users to consent to your privacy policy and/or terms and conditions? With Joomla 3.9, it’s all handled automatically. Simply and easily set up your core forms to request consent before collecting any personal data.
    You can also set up a time-based privacy consent expiration. The system will let you know if and when you need to contact your users to renew consent.
    Track user consents, manage site policy changes and much more besides, all with a glance at your dashboard.

  • User information requests? Easy-peasy
    Track and manage information access or removal requests from your users, seamlessly. Once a request is made, just log in, export their data and/or remove them.
    User data removal requests are all handled automatically, with all personal data anonymized without you needing to lift a finger.
    Never forget a request again. Just set Joomla 3.9 to remind you.

  • Extension Capabilities - Put your users in the picture when it comes to privacy...
    Extension developer – give your potential users a helping hand, by making it clear what data your extension collects. When you want to report functionality in your extensions that may need privacy consideration, simply use the new Plugin Event (onPrivacyCollectAdminCapabilities).
    With this simple action, your users gain a clear understanding of your extension, and whether they’ll need to amend their own documentation, such as their privacy policy or terms of service.

  • User Actions Log - Know who’s done what, and when
    Want to know what administrative actions have been performed on your site? Thanks to Joomla 3.9, Super Users can easily see which user did what, and when. And it also works with supported extensions! Review the action log, export it and purge the entries. You’ll never miss a trick, thanks to the latest actions module that can be added to your control panel.
    Need more? Then enable the new log rotation plugin – this will allow you to rotate and remove your log files.

The future of Joomla 3 and Joomla 4

The current plan is that the next release, Joomla 3.8, will be the last in the Joomla 3 series. According to feedback from the Joomla developers, we could expect Joomla 4.0 to arrive around six months after Joomla 3.8.  We do note however that there are still regerences to Joomla 3.9 upon the Joomla web site.


Broadband Connections

We have recently relocated and this in itself whilst being ‘fun’ has in particular provided a number of ‘opportunities’ as regards our broadband access mechanism.

Having been a BT customer for  many years our first thought was to continue using them as a broadband provider. Alas this was not possible since our ‘landlord’ didn’t want lines ‘over the property.   OK you might say, but just cancelling BT broadband was itself ‘interesting’ in that they see this as an opportunity to make money.  Not only is there a disconnection fee, but also since we paid in advance for line rental for a year they deem that any of the rental paid for the remaining part of the year is also lost. This latter cost can in itself amount to over £100 pounds.  So make a note to never pay in advance for BT services since if there is ever a need to cancel them then it is going to cost you more than you expect.

The intent was to instead make use of a cable connection.  Cable was laid to the property and all that was required was for the cable providers to come an make a connection. Sounds simple, but no, even here the cable providers fail to turn up and carry out the work, due to ‘a driver being ill’.   Strange that they only have one driver you might think, and you would not be alone. Here we are several weeks later and we are still waiting.

So we have ben forced to look at other alternatives. Many years ago we made use of a ‘wireless mobile broadband’ connection from BT.  This is effectively a dial up connection using a mobile instead of a modem.  It worked quite well but was very slow.  Dusting off the device and trying it didn’t work, mainly we suspect because if one does use a ‘mobile’ number in a period of time, often about six months the mobile number is effectively dead.   Not too surprised at this but it got us thinking and sure enough things have moved on.  Seems the current solution is ‘wireless hub’ which is a small device about a few inches square, into which one insets a mobile SIM card and once connected provides internet facilities for up to 10 devices.  These seem to be provided by most if not all of the mobile providers, and one contracts for a ‘data’ only SIM device.

There are a few things to consider.  First what is the likely usage of the data, and in particular how much data are you likely to use each month.  Often one is totally unsure of how much data would be viewed in a month, but one has to have a rough estimate, since if one exceeds the ‘monthly’ contracted usage, the use is either a) cut off for the rest of the month, or b) subject to an increased cost for the data used after the limit is exceeded.  Neither of which is a good outcome.

One contracts for a certain amount of data usage each month, and different providers have different set levels, such as 500Mb, 1Gb, 2Gb, 4Gb, 8Gb etc.   The cost is also somewhat variable between different providers.  An additional consideration is how satisfied the customers of each mobile provide are, and this alone is sufficient to eliminate a few of the possible suppliers.

Remembering our previous performance observation we were really only interested in using a 4G network. Those of you still using a portable phone on a 3G network will be aware of how slow surfing the web can be.  We selected a 30 day contract with EE for a 4G mobile SIM and so far we have been very happy with the result.  Performance wise it is faster then the fixed line speed we were used to seeing using our ‘old’ BT connection.  Cost wise, it is a little early to say, but since we are not paying for a ‘broadband connection on a fixed line’ this tends to offset tie cost a little, hence we are not really seeing a real difference per month.

Whether this is a solution for the long term, remains to be seen, but as a short term solution is is working well and should not be discounted if one ever sees oneself in a similar situation in the future. 

Joomla 3.6 released

 joomla 3 6 stable release

The Joomla project has released its version 3.6 stable package.

This new Joomla release has lots of bug fixes and over 400 improvements to make everyone's day to day Joomla usage easier.

One thing we did like was that the Joomla team has also created a made a great Joomla 3.6 microsite highlighting all the main features. Even more items can be seen in the Joomla 3 FAQ as well as a more technical list on the project's GitHub repository.

Here are some of the highlighted features:

  • Joomla update can now perform a reinstall reverting back to default code.
  • Usability improvements that help find things easier and get things done quicker with dropdown task execution.
  • New Sub form field function for developers to take advantage of.  Developers should read this as nested forms and enhanced repeatable fields.
  • On the fly category creation will make content editors happy as they can create a new item and a new category in the same process.
  • Menu type ACL gives even more control to fine-tune permissions on backend menus.
  • New option to show all items from all menus gives a quick overview of what is displayed where on the website. It makes it easier to spot duplicated links, missing menu items or just obtain an overview of every menu on your site.

There are many features to explore and remember that our components work fine with this new Joomla release!


Rialto v1.3.0 released

rialtoWe are pleased to announce release 1.3.0 of the Classified Ads component for Joomla named Rialto.

This component runs on Joomla 3.5.1 (and above). 

This release adds the ability for registered users to subscribe to receive messages about new and/or entries.  It also corrects a few problems found with the earlier 1.2.2 release. It also changes the front end entry creation to use JForms and provides some additional language options for messages..

See the change log and updated documentation for more details.

The release is available in the download area.

IP Mapping 1.4.2 released

location-48IP Mapping release 1.4.2 available.

The Joomla component came from a requirement to display IP addresses of site visitors upon Google maps.

This release fixes a few newly discovered problems.

The most important is probably that the site is no more, the code now residing upon Github.  One consequence of this is that the it is no longer possible to link to the makercluster javascript file and we have to now include it in the distribution.  The file has also had to be modified so that it no longer directs to googlecode for images.

One other change is that the policy usage of Google Maps seems to require an API key, which has caused problems on some sites, but strangely not upon others. See more below.

We have therefore introduced two additional API keys that can be specified.  

There was formally one API key which is used by the connection to the IP InfoDB server to get the location details of the IP address.  This InfoDB key is used by the visitor agent map IF the HTML5 Geolocations is turned on. It is also used in the back end of the site.

The two new possible API keys relate to Google Maps API.  One is a browser API key and the second is a server API key.  Some sites seem to require the setting of a Google Maps API key, where as others seem not to require one. We do not know why this is the situation.

According to the Google Maps API docs a browser key or a server key will work, otherwise a NOAPIKEYS message is displayed in the browser console window.  Our tests seem to indicate that a browser API key will only work IF there are no defined HTTP referrers defined. When there is one or more HTTP referrers defined, then the maps fail to load.

Our tests using a Server API key appear to work every time.  We should also add that some sites, among which we include our own, do not require an API key, and still work fine displaying the maps. Whether this continues to be the case in the future remains to be seen. It might be wise to obtain a server API key as a possible safe guard for a future Google Maps API change.

This update has only been tested against Joomla 3.5.1.

See the changelog for details.

The release is available in the usual download location on our site.

Rialto v1.2.2 released

This release corrects a few problems found with the earlier 1.2.1 release. It also changes the front end user profile edit to use JForms.

See the change log and documentation for more details.

The release is available in the download area.
