The only time I find these pop-ups is when I click on the events page, with my antivirus off and pop-up protection disabled. It doesn't happen on any other page. It isn't the act of clicking because if I enable maintenance mode on the page, the splash shows up without the popups when it's clicked. This tells me that it isn't the actual act of clicking the menu. Since this is the site's "blog" so to speak, I'm under the impression that the problem resides in my database.
It didn't get it fixed and was debating whether purchasing Sucuri would be fruitful. The fact is, I won't be wasting my money since there is obviously a security issue that's being over-looked. It got in somehow. I have very limited knowledge on databases so I am hoping to find a program that can "search" it.
