Hi there! :slight_smile:
This issue can be seen if you follow a portal link, ie. https://eliteshift.com/ca-2/whmcs/clientarea.php/?
I interpreted it as a problem with .htaccess, but this makes no sense.
I updated using your 'auto-update' feature, and it broke the installation the same as last time. According to the changelog it was version 1.0.3.
I disabled the plugin, manually updated.. and I started getting this error upon reactivation.
Any ideas? I've had essentially nothing but trouble with your plugin LOL.
