I’m getting this problem, too. Unfortunately, I’m not code-savvy enough to go an find the syntax error or the java script that might be causing it. I’m not afraid to edit a file on the back end, but I don’t know where to look nor do I know how to access the java script console. I don’t mean to be needy. But, can you possibly lend a little time to provide some direction to help me get started in the right direction?
I should probably add that my site is hosted on SiteGround and is very stable. So, I don’t think the error is caused by weirdness with my hosting service.
