I can access functions of your membership plugin from my Theme template files and from the functions.php file. However I have created a bespoke popup login form who's files are located outside of the wp-content folder which worked when I had the original membership plugin installed. However since updating to version 2 it seems I can call the function but it fails. I think it has to do with accessing the plugin files directly. Originally I used global $M_Membership and global $M_Options and wondered if this is the issue. I have tried changing to $Membership_Model_options and $Membership_Model_Member without success. Do you know how I can achieve this?
