Unfortunately, we have never tested the theme with this plugin. All compatible plugins are listed in theme description at ThemeForest.
Sounds like either a conflict with theme/other plugin or a CORS bad linking problem.
Thank you for your understanding

Hopefully we can figure this out.
The theme has 39,000 sales so it would be a good idea to confirm Toolset's compatibility and then ask the theme author to add you to their list of supported plugins.
