There was an error encountered with your upload:

Unable to move/copy file

Since you just joined vbulletin.org. I am making a few assumptions.

Do you have your directory permissions setup correctly?
Can you upload other types of files?
Under the AdminCP -> Maintenance -> Diagnostics -> Upload (File Test). --- Did you run this?

Anyway, a starting point. :)

Is there anything in your error_logs (if you don't know where they are, ask your host)? Do you have safe_mod enabled on your server? Are avatars in the database or filesystem? Is it only avatars that have this problem or attachments also?
