The issue you are facing:

Upgraded from 21.0.4 > 21.0.9 Sync to clients OK but web says “Internal Server Error has occurred”. Continued to upgrade to 22.2.5 and then 23.0.2 - same web error. Noted on comparison to working server, that “index.php” missing from web url ?

Is this the first time you’ve seen this error? (Y/):Y

Steps to replicate it:

  1. Upgraded using updater/updater.phar

Sorry no real idea. But can you execute this command in shell and the correct path /path/to/nextcloud? Sometimes we get additional errors.

php index.php

OK so I started looking into the .htaccess file(s) and found each one in the backup folder increased with each version upgrade.
I checked the .htaccess folder on my home (working) environment and found that below the line that says #### DO NOT CHANGE ANYTHING ABOVE THIS LINE #### there were only 2 lines (on working server) and MANY lines on NON working server.

I deleted all the lines below :slight_smile:
ErrorDocument 403 /nextcloud/
ErrorDocument 404 /nextcloud/

Restared Apache and Voila ! it is alive again.

Not sure how / why these lines of code were introduced and why post upgrade they failed, but right now - working successfully on 23.0.2 on Rocky Linux 8.5

Very happy !
