Unable to edit certain pages – potentially a javascript error

Hi,

My site was created many years ago. I’m trying to edit pages. Some are having issues generating the content for me to edit when I use the Enfold theme. If I change to a different theme the issue disappears.

I have tried updating all plugins, deactivating plugins, clearing the cache but have had no success.

Please help!

Here are the error messages:
