You’re a star, thank you! It worked!
Did you figure this out? I’m having the same issue.
Anything before <InnerBlocks /> displays on the editor and front-end. Anything after that element displays on the front-end only, but not the editor.
We’re having the same issue here, only we’re not using Gutenberg, just regular Classic Editor and WYSIWYG blocks.
The console shows:
TypeError: r is undefined tinymce.min.js:17183
Any fix for this? It happens on dev and staging, although not on all sites using the same theme code / ACF Pro version.
