Backend styles broken in TYPO3 v7.3
I want to ask if the issue is already known, that the backend styles are broken using the TYPO3 v7.3.1. I have made a screenshot.
The strange thing is, that it works on another installation. The diffrent is, that where ist works is an upgrade from TYPO3 v6.5. The current where it doesn't work is a clean installation.
I tried already deactivating all other extensions (including cache clearing ;) ). Just at the moment gridelements is inactive, it works correcly again.
