Hi,

I'm trying to configure a pop on my site with an image.
unfortunately the image does not show up and instead I get a link that looks like this \"\"
that point to http://searchandtravel.com/wp-admin/%5C%22http://searchandtravel.com/wp-content/uploads/2015/07/Search-and-Travel-220-x-60-BW.png%5C%22

Thanks,

David
