Hi Thinker. I was just about to post something on this same problem and the I saw your post just today on the subject already. I clicked on your link and the ads do not seem to be repeating so it seems you got the problem solved?
Anyway, I got the same problem with ads duplicating, but I don't have a permissions problem like you did. I am running it on a test board here where you can see the add also duplicating:
http://www.photographythailand.com/Forum/index.php?board=31.0I am not sure how the theme would have gotten duplicate code embedded like ITA003 suggested, when we are both using the default SMF theme and not a 3rd party theme.
If you have managed to get it sorted out, then I would appreciate hearing how you did it.
Many thanks.
Marc
