Upgrading my Theme to the latest version broke the Slidetabs plugin

Upgrading my theme has broken a plugin I use called Slidetabs

I’m getting the following javascript error in my browser console when I try to add a new tab:

TypeError: settings.data is

. . . /wp-content/themes/enfold/framework/js/conditional_load/avia_google_maps_widget.js?ver=1.0.0

Line 27

It seems to be an issue with the theme/framework (Enfold). It’s causing a conflict with the Ajax function that adds a new tab editor.

But I don’t know how to address this issue.
