I recently changed my avatar to one I had used before, and it seems to be displaying my old STOP SOPA avatar in the forums. It looks right on my profile and on the Yo Luis! Dashboard | Inbox | Logout bar up top. Help?
If I could guess anything, it would be because the file you uploaded for your avatar has the same filename as your old avatar.
Re-save it with a different filename or put it in a different folder. That would probably fix it.
This happened to me. I was using the same filename.
So, I think Chris is dead on in this. With me, the one I was trying to upload briefly showed up on the Dashboard | Inbox | Logout bar and my profile sporadically, but that corrects itself.
I’d recommend changing the filename and re-uploading.
