CKEditor not loading since 9.5.6
We just updated to Typo3 9.5.6.
Custom RTE fields are now rendered as simple textareas without RTE and without error message.
Things get clearer when we try to use our custom RTE-YAML-definition. The YAML definition wants to import base functionalities of the CKEditor extension. This creates this error message:
#1485784246 RuntimeException YAML File "EXT:rte_ckeditor/Configuration/RTE/Processing.yaml" could not be loaded
Could this be due to the new security features?
