There are a lot of intrusive ads this season. If one messes up the formatting of a page, especially on the guide (chef boyardee) hit control + F5 and it will usually fix it. Sorry, there are so many differing ads that there's little I can do. Thankfully I haven't seen too many ads of the naughty nature lately
Edit: Also, if you have over 50 posts and see the guest ad let me know! Sorry for new folks, but its removal is a perk to look forward to when you have achieved Jr. Member rank.
