Hi, same issue here than others :
Once I have uploaded and activated the Gravity Forms I get the following error message whenever I try to add a form, edit settings or anything else "You do not have sufficient permissions to access this page."
I don't have any role manager activated, and check on phpmyadmin to see the level of amdin or my user and it appears correct (to 10) I also see gravity full access on php my admin.
For your information, this trouble appears with no other plugin than gravity AND tdo miniform (i also tried this one).
Any hook to fix this quickly please ?
