On further inspection, I've found that the problem only exists in the Google Chrome browser. Firefox & Edge both work properly allowing the logo and menu to float over the facebook post box. Sorry about the link... it had a typo. It's www.campconn.com/wpCCOA/
Do you know of a way to make it work properly in Chrome? Firebug is not helping much because, as I said, it works properly in Firefox.
If this is not something that you can help me out with, I understand. I just thought I would ask.
