Hello Jørn,

thank you for the update.
We started installing our production server.

I used simplesamlphp-2.3.8 instead of simplesamlphp-2.3.6 (running on 
the test server).

It resulted in a Server error 500 on the "/app/" page.
Is this a known issue?
The apache error log is pointing to twig as problem.

If I switch back to simplesamlphp-2.3.6 it works.



In addidtion we realized this error message on every web-call (even with 
simplesamlphp-2.3.6 on the testsystem) while running fine:

[Fri Jul 18 06:54:55.165662 2025] [proxy_fcgi:error] AH01071: Got error 
'PHP message: PHP Warning:  Array to string conversion in
