Steve, Thanks for catching the inadvertent override of iframe. That was a very old part of the site that I had forgotten about.
Posting a comment appears to be completely unresponsive. No error messages (that I can see), no response, and nothing in the database.
Also, I noticed that filer.js now throws a new error (see below). Might this also be related to jquery 3.1? Since you disrtbute jquery 3.1, that was the last thing that I would have thought of.
Thanks, David
