Got some embarrassing access denied error:
[Fri Mar 24 13:15:32.617410 2023] [access_compat:error] [pid 14599] [client ....] AH01797: client denied by server configuration: /home/Albums/jAlbums/Bilder/
Tracked the error down to APACHE_MODULES including mod_access_compat without making explicit changes. Removing this module from APACHE_MODULES and restarting made apache great again.
