Hi,
I have added a Team Page like the Stuff page in the Tutorial.
Offline this works great but online on uberspace i get an internal server error every time i try to switch between pages in the admin panel. Accessing the same page direct works without a problem.

The failed ajax request: https://www.dropbox.com/s/p68y361i5d6ygcu/Screenshot%202014-01-05%2018.00.59.png
I enabled the dev mode and php error logging but no errors get logged, my Apache error_log is also empty.
I made a clean install and only added the TeamPage.php file.
When i comment out the line with new UploadField everything works.
