“Appearance” button missing from dashboard

My appearance bar and all of the included functions have disappeared from my dashboard. I can no longer edit widgets, themes, or code or do any other functions normally found under “appearance” on the dashboard.

Otherwise, the site appears and functions normally (www.hainesnews.org)

I’m using alibi3col theme with 16 widgets, and have some plug-ins including polls and WP-SpamFree that I have placed in widgets. Most recently I turned on the ratings function, added an html paypal button inside of a widget, and have been working with a formsite html form builder (www.formsite.com) in a separate page. My recent upgrade from WP 2.9.1 to 2.9.2 didn’t solve the problem.

I would try disabling the add-ins, but don’t have access to them through the dashboard menu.

Any ideas?
