Since I installed WordPress 3.9 and TinyMCE Advanced 4.01 I've seen a strange error. Anytime I make any change to any page and click on Update I get the message "Are you sure? This page is asking you to confirm that you want to leave - data you have entered may not be saved." I click on Leave Page and the changes to the page are saved and WordPress stays on the page. If I deactivate TinyMCE 4.01 the pages still save just fine and without the above message. Any ideas how to get rid of this. I am not attempting to, nor do I, leave the page. The web site is http://cjfd.org. Thanks in advance.
