@anoek is it intended, that we cannot access the API in a browser tab? 500 is very generic (and probably wrong). It makes development much harder.
All attempts to edit tournaments return “Server Error (500)” when saving.
Quick test showed tournament could be edited while there were no participants.
When there are participants some things are changeable while others aren’t.
This looks like a deliberate change to me that maybe isn’t quite finished.
Whoops, those issues should be fixed, I have been upgrading various libraries and I missed a dependency
