In less technical terms, the problem is that the server won’t let Bavatars make its folders because of folder permissions. All I’m telling you to do is make your forum root writable by the server, deactivate and reactivate Bavatars to let it make the folders, and then change the forum root back to the way it was.

If you don’t want to do that, make a folder called avatars at the forum root and set it to chmod 777. De- and re-activate Bavatars, and your problem will be fixed.
