We tried to place the tribalfusion popup code in our discussion forum website's footer or header but it didn't work. Is there something we still need to do with the actual popup tag given by tribalfusion to make it work?
I would definitely work on header or footer. But on forums tribal fusion does not have very good fill rate pop up under ads. Just wait for 2-3 days and check your reports you would be able to see some entries for pop up ads. I my self have seen popup ads on my forum only twice in last 2 weeks.
