I seems I made it work by: Not only going into pbwow, but also the templates etc for the specific theme I'm using. In my case, I went to the Crusader theme, and found as many files with the ad in it as I could, that was significant to my issue.
For example: pbwow_crusade -> viewforum_body.html pbwow_crusade -> template -> viewtopic_body.html
and so forth. It seems to have helped (this isn't mentioned in the OP though ).
