Avatars, all other plugins not working

I'm sure I'm missing something simple, but after hours of search, I can't find what it is. I've had Avatars, Recent Global Posts, and other plugins working great.

I recently upgraded my site to 3.0.1, installed the new version of Avatars (carefully following, checking, and triple-checking the directions), but nothing appears in the users menu to upload an avatar. Tried installing Recent Global Posts, and that also does not appear in the Widgets (I'm assuming because Avatars isn't working). I do not have buddypress installed.

No php errors are showing in the error logs. Site is http://werunforgood.com. htaccess is as follows

RewriteEngine On

Not sure where to look anymore! Thanks for any help you can give...
