I can't seem to edit certain plugin settings now that I've upgraded my site to WordPress 3.3. I can get to all the settings pages under the Settings menu. I can not get to settings pages that are under their own menus. When I try to access different settings pages, I get a message that says:
You do not have sufficient permissions to access this page.
This happens on plugins like "Email Users", "Mingle Forums", and "WP Forum Server." I know Mingle Forms and Email Users worked just fine on WP 3.2.1. Not sure what changed and what I should do.
