Link to a page where the issue can be seen: Can provide in private
I expected to see: $("#serviceGrabber").multiselect("refresh");
Instead, I got: $(\"#serviceGrabber\").multiselect(\"refresh\");
When I save the page the quotes are being escaped in the JS Editor - breaking all of my JS. When I save again after that it looks like it is escaping the backslashes it added last time so it is exponentially escaping characters in the JS.
This happened only after updating all plugins.
Duplicator plugin is not permitted on the server where I host. I have backed up before updating plugins.
