'Column Text' from Tagdiv Page Builder Broken – Cannot Add Shortcode to Page

Hi,

I’m trying to add shortcode from an external plugin into a page created by Tagdiv. The way to do this is to add it with ‘Column text’ or ‘Text with title’ from the Tagdiv page builder.

Both of these options appear broken. Drag and drop is ok, and editing the style is ok. But ‘Edit Content’ (where I would add the external shortcode) is stuck in a loading loop. Has been for days now – tried deactivating plugin, refreshing, clearing cookies, on/off etc.

How to fix this? I need to add shortcode to this page.
