What might cause the text editor (CKEditor 5 / TinyMce) not to appear in certain text fields set to use the editor?
I have several custom blocks that were created early on with CkEditor 4. They work fine, but if I try to edit them (or create new ones) there is no longer a text editor, only the bare text box. Same thing with any summary fields for page/post/or various content types, even though the summary fields are set to one of the html formats.
The same is true for comments, whether logged in or out.
None of the body fields in various content types have this issue.
I realize this could be caused by any number of variables, but would appreciate any ideas on where to look. I have checked through permissions and have tried changing text formats and even editors, but the issue remains.
Here's the add a custom block form set to use filtered html. The CKEditor toolbar doesn't show:
Could be a JavaScript error. You could inspect the page (right click on the page and select Inspect - something named like that) and see if there are errors on the console tab. Might provide a clue.
