Problem display to the initial value of the editor

Is there a problem ?

In code, when I edit an element in the $ w.onReady function, like changing a text for a title, it works 5 seconds and after, all elements change to the initial value of the editor

I cleared the browser cache and this problem is the same.
I’m checking into a new, blank website, and this problem is the same.
I check in another browser (from chrome to firefox) and this problem is the same.

This problem has occurred for about 1 hour
Is it your server?
we can not continue to work

Thank you
