I just have bought Easy Profile PRO
After updating version 1.3.15 I tryed to create new Group corresponding to Joomla user group.
I probably delate some DEMO group which appear in trash but not editable.
When I try to create new group or new fields, I still have an error
Error : Default core fieldgroup must be visible in Registration and edit profile pages, so you need to add some field visible in both pages
I don't success to repair the problem and active easy profile.
Thank you for your help
