Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 20.0.5): 28.0.2.5
Operating system and version (eg, Ubuntu 20.04): ubuntu-server 22.04.3
Apache or nginx version (eg, Apache 2.4.25): NGinx 1.25.3
PHP version (eg, 7.4): 8.2.15
The issue you are facing:
After update from NC 27.1.6 i had several config warnings concerning
- missing nginx support für mimetype *.mjs (done by adding this to nginx config)
- missing config.php parameter for maintenance_window (added parameter to config.php)
- and resisting messages for logfile entries concerning missing class TrashManager (yes, i opted out the app “deleted_files” - and it was ok for NC 23…24…25…26…27 — but not for 28 ?)
So i checked the logs and it opens everytime with the shown message (see picture above)
After few seconds the message disappears and my logfile entries come along.
I have cleared my browser cache, server has been restarted several times inbetween but this message is shown reproducable but i have no idea.
My config.php is configured to log into /media/cloud/data/nextcloud.log
This file has unix rights set to 0640 and owned by www-data:www-data so as before and should be ok so far, no?
I can watch logfiles and activity log as well, so my changes to mime.types in nginx config shouldn’t be the issuer.
Is this the first time you’ve seen this error? (Y/N): Y (since update from 27.1.6)
Steps to replicate it:
The output of your Nextcloud log in Admin > Logging:
no logs concerning the message seen in the screenshot, only concerning the missing class for the TrashManager (see another post of mine yesterday)
https://help.nextcloud.com/t/queryexception-could-not-resolve-oca-files-trashbin-trash-itrashmanager/180560/2
The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):
