When using a WYSIWYG field in a content type, the form ("Site" view) does not load on the front end; instead the following message displays over a Joomla's broken page background:
count(): Argument #1 ($value) must be of type Countable|array, null given
Experimented with different combinations, and when I remove all WYSIWYG fields from the form/Site view, the form renders just fine; when I add just one (or more) of these WYSIWYG fields back in, the same error shows up.
Tried to implement a solution described, e.g., here, but no dice.
Thoughts? Thx much!
