MariaDB error 500

(Sorry, I don't know English! Translated by Google Translate).

I am experiencing problems with MariaDB web access generating error 500. When checking the logs I found the following error:

Code:

I couldn't find anything that helped with the solution.

What applications have you installed on that system? What is Symfony?

 

Thanks for the feedback!

Report as requested.

Now what Symfony is, I'm not sure, but it's something linked to PHP. I found this related site symfony.com.

Regarding applications installed on the server, I have docker, webmin and openvpn, but the latter is disabled.

##### IPTABLES #####

##### LET'S ENCRYPT #####
[WARN] You have both certbot and acme.sh installed. This can lead to problems.
Certbot: /usr/bin/letsencrypt
acme.sh: /root/.acme.sh/acme.sh

 

Please fix your system default php.

Also ensure you only have one LE client.

 

You seem to have installed lots of stuff in addition to ISPConfig. ISPConfig is a control panel to manage the server or servers, you should not install additional management software.
Is this a recently installed system? It might make sence to start with an empty server and install a plain ISPConfig system to get rid of the extra bits.
If this is an important production system, you may have a lot of work to do to get it sorted out and working reliably. Like @ahrasis wrote, the system default PHP version is wrong, read the read before posting -article from start to finish.

 

I identified the problem reported above. It was fixed by removing the Apache proxy_fcgi module.
