WordPress 4.8’s visual editor not working

Hopefully someone can help with this. The reason why I’m posting here, is because after doing some research this thread mentions the issue is with using the TinyMCE visual editor with two different editors…the thread on StackExchange specifically mentions PageBuilder…so I came here hoping for some kind of a solution:

https://wordpress.stackexchange.com/questions/269853/wordpress-4-8-using-multiple-wysiwyg-editors-with-media-inside-of-widgets-how-t

Anyway, here’s the error I get in the JavaScript console:

Uncaught TypeError: Cannot read property ‘onpageload’ of undefined

at HTMLDocument.p (tinymce.min.js?ver=4603-20170530:2)

ALSO, the visual editor in PageBuilder has issues too. None of the dropdown menus work.

I’ve tried deactivating all my plugins…but the issue still seemed to be there. One thing that DID work was installing a fresh version of WordPress, installing the exact same plugins, and pointing the Troubled Installation to use the new database. In that care the new editor worked…but I didn’t have any of my pages/posts.

Sorry for the length of this, but thought someone might be able to provide some insight. Thanks!
