Problem 1
I upgraded a D8 multisite to D9.
CKeditor toolbar works fine on the single-language sites, but in the multilingual site the CKeditor toolbar doesn't show up in most of the node edit forms. :(
I can use the 'Quick node clone' to replace all those nodes so they display the CKeditir toolbar in the new edit forms. Lots of work.
Problem 2
Call to a member function filters() on null in Drupal\ckeditor\Plugin\CKEditorPlugin\DrupalImageCaption->getConfig() (line 63 of /xxx...xx/drupal9/core/modules/ckeditor/src/Plugin/CKEditorPlugin/DrupalImageCaption.php)
Warning: assert(): Cannot load the "filter_format" entity with NULL ID. failed in Drupal\Core\Entity\EntityStorageBase->load() (line 244 of /xxx...xx/drupal9/core/lib/Drupal/Core/Entity/EntityStorageBase.php)
Having mentioned this, after I have saved first the new text format without CKeditor, after opening the text format again I can see the CKeditot toolbar options...
What is going on here?
What can I do to solve this problem/these problems?
Best wishes,
Jippie.
