XF 2.2 Error 500: Website not working

[Sprisa]

Hello! I can't access my xenforo installation after some time not checking it out. My os is Ubuntu 20.04 and webserver Nginx.

 

[Sprisa]

All of my pages return 500

 

[Paul B]

A 500 error is a web server error.

Contact your host and ask them to investigate.

Its my own dedicated server, are there any error logs in xenforo btw?

 

[Paul B]

You will need to investigate then, starting with the server error log.

Looks like my database died

 

[Paul B]

Call to undefined function mysqli_init()

You or someone else with access to the server has removed mysqli.

 

[TPerry]

Are you running a cPanel (or any panel) interface and did an upgrade to a new version of PHP recently?
I have seen similar happen when the appropriate PHP PECL's were not bundled into the upgrade of the PHP processor.
Did you set up the Ubuntu instance yourself and then "roll your own" with nginx/php-fpm?
Depending on answers provided, I might be able to help with this as I have time (at no cost).
It's been a while since I've used Ubuntu (I do have 2 instances running at a local medical clinic in VM's, one for TimeTrex and another for NexCloud) as I normally use CentOS (and CentMin Mod) but have moved over to AlmaLinux and the BETA of CentMin on my current sites.

Does xenforo create backups of database?

 

[Paul B]

No.

Backups are the responsibility of the site owner/server admin.

 

[Sprisa]

No.

Backups are the responsibility of the site owner/server admin.

Rip then

 

[Sprisa]

because looks like my database corrupted

Not necessarily.. those logs you showed indicate that mysqli PECL is NOT installed. Have you confirmed that it is?

@Sprisa You learned something important today! And don't forget your files on the server (especially /data and /internal_data)... I hope you can recover your database and that this time it's nothing serious.
