TYPO3 Core

The middleware SignalSlotDeprecator requires a constructor parameter $dispatcher. However this paramter is not provided. This raises an exception which makes the backend and install tool unusable.
I could formerly log into the TYPO3 backend. Then I activated an extension. Later I deactivated this extension again. I have also removed all the typo3temp cache code files.
