When updating the plugin, the profile form with an avatar field is no longer working. It's not possible to upload any file (error #-600: file size error), and the users that yesterday showed their avatar are not showing now.
If I deactivate the plugin, the avatars are showing again: in the users menu, and at the top menu dashboard when users are logged in.
Yeah, sorry for that. Previously the avatar url was saving like this: /2013/03/image.jpg. But now the complete url is saving in the avatar meta field to fix the multisite issue. Somehow you've to fix those image urls.
