For the last few months I’ve been having issues with pop-up ads showing up on my blog. Originally I thought it was a bug with my new favorite commenting system, @LiveFyre, but that was ruled out. They were even kind enough to look around my blog for the problem and couldn’t find it.
I’ve done just about all that I can think of. I manually went through my WordPress database cleaning out extra tables and entries down to the bare essentials. I got rid of all my plugins and themes, deleted every orphan database entry, wiped my WordPress install and even got my host involved.
