Prior to release 1.2.3 the determination of the geolocation information made use of a PHP function that required the setting of the 'allow_url_fopen' to be enabled. This is considered by some to be a potential security problem and a number of sites may have this option disabled. To enable it one can place a command in the php.ini file.

Release 1.2.3 added the ability to automatically use Curl as an alternative when communicating with the geolocation provider.
