I have repeatedly tried to load, unload, and activate my GP Premium Serial# on a WordPress site that is a sub-domain of mine and cannot get it to Activate. I have added this URL to the list of “Authorized” sites in my Manage Licenses area. It works fine on my Primary Domain (http://downrangeopns.com), but won’t work on my Sub-Doamin (http://downrangeopns.com/support/).
My host has been working with me to resolve this issue and have upgraded my server PHP with cURL. Without success!
