lol, what the hell. That is definitely not a part of the forum, or shouldn't be anyway. I'll look into it a bit more. Have you checked to see if your phone has any malware or spyware on it? It can happen. Almost looks like something that's browser-side, but I'll look through the back-end a bit to make sure something isn't messed up.
Actually, can you do me another favor. Can you highlight the link and post the URL. Hopefully you can do it without actually visiting. I've looked through the style templates, and wasn't able to find anything based on the screenshot. If I can use the URL, or even part of the URL I can do a search in the template to see if the URL is being used at all.
I'll have to do that tomorrow. It only happens once a day and once I close it, then it stays closed. All things on my system show no malware or virus' on my computer (Malware Bytes, SpyBot Seek & Destroy, & MS Security Essentials). I figured it was something with the new "banner" that was added.
