Hi!
You could be right but I’m actually wondering if the problem is not with Divi itself but rather with a customization that has been made to it.
Are you aware of any changes – perhaps customizations to one of the templates or extra code in the functions.php file – that might have been made, whether by yourself or a developer working on your behalf?
It looks like a script called angelo.js is running but it lives in the root of your WordPress installation (which is why I suspect it isn’t related to the stock theme by Elegant Themes).
Would it be possible for you either to temporarily remove this and any other customizations/tweaks (or even revert to a pristine copy of Diva) and see if there is still a problem?
Thanks!
