I’ve just done an composer update on my ddev lokal system. Typo3 is updated to latest version 13.4.12 and Content-Blocks ws updated from 1.1.9 to 1.2.3.
Now I get an Error in my backend, that seems to be related to Content-Blocks.
Cannot modify protected(set) readonly property TYPO3\CMS\ContentBlocks\Definition\ContentType\ContentElementDefinition::$identifier from scope TYPO3\CMS\ContentBlocks\Definition\ContentType\ContentTypeDefinition
Is there a bug? What can I do?
You need to clear all caches. You can do that either on CLI with typo3 cache:flush or in the TYPO3 install tool.
Check the documentation for more details on Clearing/flushing and warming up caches
It’s always a good idea to clear the caches after major code changes, e.g. when updating an extension or the TYPO3 core.
Thank you.
I did that, but I had a misspelling in the command and the error message did not tell me that. Unstead I’ve got the message above which led my thoughts into wrong direction.
