[Plugin: Advanced Access Manager] Permissions problem

Hi. I’m trying to alter the editor role to restrict various menus. Now, when I try to log in as an editor, I get “You do not have sufficient permissions to access this page.” and the rest of the screen is blank. Logging in as admin works fine as normal.

What could be the problem? Is there a setting which stops a user from being able to log in?? Thanks
