It’s extremely long! Too long to fit it in here, how do I even figure out what is relevant?

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

The output of your Apache/nginx/system log in /var/log/____:
No such log, nginx folder is not accessible through MobaXterm for some reason.

I have little to no experience in working with Linux/Unix so beware.

It isn’t written that you should post the whole log file here, but the related messages.
If you stop your web server, empty or move away the existing Nextcloud system log file, restart your web server and again try to login to the server again once, you should find only a limited number of log messages.
In most cases a required php module is missing or your server and need to be installed, so focus on “error” messages first.

Hey j-ed, I just did what you suggested, here is the log from one try to sign in.
Thanks for your help :frowning:

Using the search function of this forum I found the following hint:

Thank you for the hint, I’ve edited the personal.php like suggested but with no success.
Assuming that there are probably some general compatibility issues I was trying to uninstall files reader through bash with the following command
sudo -u DerTony php occ app:disable files_reader
but getting the following error message:
This version of Nextcloud requires at least PHP 7.2
You are currently running 5.6.11. Please update your PHP version.

Which is leaving me confused because I thought Nextcloud is using the PHP version provided by the backend on my DeskStation. And I have Apache 2.4 and PHP 7.3 installed on there.

6

That is the usual problem using a Synology NAS, because it handles the php-web and php-cli component differently. As far as I remember you cannot use the “php” command on the console and need to use e.g. “php72” etc. The search function of the forum should lead you to Synology related issues.

7

Yes, and I knew that was gonna cause trouble but the user has barely enough space for the NAS and nowhere to put an extra Linux server machine with enough resources and proper setup like I suggested. I will try to get rid of that app and see if I can get it back running at least.
Thank you for your help!

You should try to use “/usr/local/bin/php72”.
