Deactivated all other plugins and even switched to the standard WP theme Twenty Sixteen, problem still exists.
Here are the steps to reproduce the error:
- Create new field group
- Create new field, type WYSIWYG-Editor. Leave all other field options on default
- Create rule: Taxonomy is Category
- Successfully add a new category term in Posts -> Category
- While trying to re-init TinyMCE for the WYSIWYG field, JS error is thrown
If you set the “delay” option for the WYSIWYG-field to “yes”, the error is not thrown after a term was added, but when you click on the field to init TinyMCE.
