When a user hits the save button the content saves however when the editor reloads it loads up the content that was present before the user made any changes to it. This makes it look like all the users changes were just deleted. If you simply refresh the page the correct content is displayed. However if the user does not realize this they may waste time redoing their work several times until it's displayed correctly or they give up.

 

This is not a 100% chance. I rarely experience it on my computer while other clients have reported as low as a 10% successful save rate. Meaning it's erroring out for them 90% of the time. As you can imagine this is unacceptable to our clients and to us.

 

I am unable to reproduce in your demo however I am also unable to reproduce in my environment.  I have seen others reproduce it however and we are getting more reports than we would like. You should be able to reproduce it here.

 

This is the first time in the past year we have seen this problem and we haven't changed anything where we are seeing these problems since July 18th.  Any help or advice would be greatly appreciated.
