I cannot access the config options of any of my WP plugins from the admin menu. I receive the "You do not have sufficient permissions to access this page." error message. I cannot access Akismet or any of the other dozen or so plugins I am using. I can access my admin menu and all other options.
I have searched for hours and have tried every solution I can find. I have set my db back to an older version in the wp-admin/options.php page and then upgrading the database. I have checked my database and I have a dedicated WP database with no prefix on my WP tables. I have checked the plugins for admin_head to replace with admin_menu. I have made sure the plugins directory and plugin folders have 775 perms. Nothing has worked.
What would cause all of my plugins to deny access in the admin panel? When I upgraded to 2.8.6, I did so from within WP. Honestly, I haven't tried to change my plugin settings for a couple of versions so it may have happened a couple of versions ago. Help?!!
