Nextcloud version: 23.0.12
Operating system and version: Raspbian GNU/Linux 10 (buster) armv7l Linux 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l GNU/Linux
Apache version: 2.4.54
PHP version: 7.3
The issue I am facing:
Internal Server Error
The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.
More details:
I was attempting to upgrade PHP to a newer version so that my instance could upgrade to a newer stable version. However, I accidentally upgraded to PHP 8.2, which is too high for any stable instance. However, everything appeared to work given the server merely said the version of PHP was too high. Therefore, I downgraded and tried to install PHP 7.4. When this failed spectacularly, I decided to give up and go back to a working Nextcloud 23 instance on PHP 7.3. However, I have not been able to resolve this issue. Interestingly, a standard phpinfo.php file will not load on my static site under /var/www/html. I am indeed using Apache, as well as Cloudflare (which is not affecting the error, since it is the same on my LAN)
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Visit the Nextcloud instance
Steps I have already taken to try and fix the error:
- Ensure the proper PHP packages are installed (including optional packages)
- Ensure the redis socket can be connected to
- Add extension=xxx to my php.ini file(s) (didn’t work, reverted)
