Ken,
I was able to narrow this down to only occurring when our 'Open Graph - Content' plugin is enabled and wanted to test a code change for it. I can tell you the lines of code to change or I can install a new package for it, but my backend permissions need to be updated so that I can be allowed to install that.
Also, if the change does not fix the issue, I will need to have access to look at the JFBConnect configuration, Open Graph and Social areas for my user. The permissions for JFBConnect can be set up by going to Components > JFBConnect > Overview and clicking the Options button and changing the permissions for Access Configuration Area, Configure Social, Configure Open Graph.
