Is there a host name configured under admin -> settings -> host name?

There wasn’t a defined hostname. Now there is. And Activity works.

Thank you!

Ok, glad it’s working now. It’s definitely not good that it results in an internal server error if there is no host name defined, though. In any case a more useful error message with a pointer to said hostname setting might be helpful.

I’ll see to it that we improve that.
