I don't know how or why, but there is a "Launch Demo Modal" button randomly appearing throughout my site, but only for anonymous users. It seems to only appear in the main content column, but I'm unable to find any block that controls this item.
Using Firebug, I can see that it's a Block, but there are no blocks in my list that have anything to do with modals. And why is it only appearing for Anonymous users??
Can you please point me in the right direction here?
