When I installed 3.3 some of my plugins stopped working. I get the following error message when trying to navigate to subpages on plugins that nest below the Settings tab at the button of the admin pages:
"You do not have sufficient permissions to access this page."
For instance, when I click on the main WordPress SEO page, I get the welcome page, but if I use the menu to click on "titles" or some other sublink, I get the error. It happens on all plugins that occur below the settings tab.
I have tried repairing and optimizing database tables but this did not help. I also changed permissions on the plugins folder, but this didn't help either.
It has something to do with my databases, because when I install a fresh install of wordpress the plugins work properly on my server.
It's not a matter of clearing old data from the db in the old plugins. When I install new plugins the same thing happens. It's something to do with the database and wordpress I guess. I dont' know. Someone help, please?
