I am experiencing the same issue for all visitors/non members and for all roles except the admin. I am running 3.3.1.
This is a great plug in and I would love to get a fix for this. Please keep us posted on the status.
I am getting the same error. All of the Category pages on my live site are displaying a white page with the words “Unauthorized Action” when I have the Advanced Access Manager Plugin activated.
This issue occurs for all visitors to the site and it also seems to occur for all registered users except for the Admin.
There is another post that identifies this issue as well.
