Maintenance work on the TU Homepage

Unfortunately, we had to cancel the TYPO3 upgrade. The backend in version 10 will be available to you again soon.

We are still looking for the exact cause. We suspect that it is due to the interaction with the file storage.
We are doing our best to fix the problem as quickly as possible and plan to carry out the upgrade next week.
We therefore have to block the backend again next week, but for a shorter period of time.
We will let you know as soon as possible and will of course take all your work in the system into account when upgrading again. Nothing will be lost.
