transparent floating boxes on page

It looks as if it’s an iframe trying to add facebook stuff.
Search through your code for #fb_xdm_frame_http and #fb_xdm_frame_https. I’m guessing these are put there by a plugin. So first thing you may want to test is disable 1 at a time any facebook plugins you have.

thank you Richard! I will try that. I appreciate your help!

seems to be caused by the ‘share this’ plugin – deactivate the plugin, or at least the facebook part of it.

yes – thank you! I deleted the FB reference in the footer and the issue went away. I appreciate both of your help(s) very much!
