Dear all,
when someone tries to register to one of our events he or she will get the following error:
Has anyone an idea what is wrong with this registration form?
Best,
Barbara

Can you please check (or have someone with server access check) indico.log on the server for the full error and its traceback? It’s likely a trivial fix, but without knowing where exactly it comes from, it’s pretty much impossible to fix
Hi Adrian,
I will forward you a private message with the error.
Thanks, I’ll paste the non-sensitive parts of it here for the sake of completeness:

Thank you!
I don’t see an accommodation field in your registration form, but the error comes from the code related to that field. Do you have one that’s either in a manager-only section or disabled?

Thank you very much! We revised the accommodation and now it works. 
it’s still a bug so an answer to my question where exactly that field was would be helpful to reproduce and fix it 
We overworked this registration form on Tuesday and decided to disable the “No accommodation” field since there will be no guests without accommodation for this group. Everyone should stay in the “Erbacher Hof” or an alternative housing if they do not have enough rooms for this time.
Yesterday, after becoming aware of the issue with the accommodation field, we enabled it, and then it worked.
ok, so i managed to reproduce it: it happens when the accommodation field is in a manager-only section AND has the ‘no accommodation’ choice disabled
