Christian,

  We are also launching letswifi-portal this summer.  Thanks Jørn for all the outstanding work in the beta branch!

  We hit the 500 and resolved it.  I believe we resolved it with a "composer update" inside our /usr/local/share/simplesamlphp and /usr/local/share/letswifi-portal.  It updated several things but I suspect the Twig 3.21.1 update resolved it for us.  We are actually running RHEL 9, PHP 8.1.32, simplesamlphp 2.4.2.  Feel free to reach out to me directly off list.  We are still actively building the systems and testing.

  We still do see similar warning though:

[18-Jul-2025 11:13:41 America/New_York] PHP Warning:  Array to string conversion in /usr/local/share/simplesamlphp/vendor/twig/twig/src/Template.php on line 359

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
