'sufficient permissions' for /wp-admin/

Greetings,

I’m a bit at a loss; my site is giving me an error, “You do not have sufficient permissions to access this page.”, upon trying to access various parts of my backend.

I have:

• Logged out and back in;
• Cleared the session tokens for my user in wp_usermeta;
• Reinstalled WordPress;
• Not changed the table prefix, moved the site, or changed any file permissions;
• Ensured correctness of wp_capabilities and wp_user_level –‘a:1:{s:13:”administrator”;s:1:”1″;}’ and ’10’, respectively.

This just seemedto come out of nowhere. Any help would be appreciated.
