Hello Matteo
I apologise, the topic that I meant is this one https://moodle.org/mod/forum/discuss.php?d=362075.
Thanks for sharing the links with the php bugs, I will look at it later.
For the moment here a few more informations:
- We have two instaces running the same setup with the moodle release Moodle 3.2.5+ (Build: 20170928).
- One of the platform doesn't show any errors like on the other platform. And they have installed the same php version/packages.
- The stacktrace of the failing platform is:
- Notice: Undefined offset: 0 in /var/www/html/<path>/lib/accesslib.php on line 3665

The error is because the array is NULL and then the roleid is not set! I've noticed yesterday when I was debugging in the accesslib.php, that the capabilities array is set different. Most time there's only the "moodle/site:approvecourse" capability set! The search was only working when in the caps array, the capability with "moodle/site:config" is set too.
PS: When I disable opcache in the broken platform It runs well!!! But the healthy platform has the same opcache configurations like the others one. Can it be, that something in the "mdl_config" is misconfigured?
Kind Regards
Adrian
