phpMyadmin not working (displays "page not found")

[spacing]

Hello there,

I have a server with a VestaCP installation on which phpmyadmin is not working, domain.com/phpmyadmin and ip/phpmyadmin both display connection refused as if the url didn't even exist.

I was only able to access it through VestaCP phpMyadmin button on the db area which goes through the url ip/list/db/phpmyadmin . Even then, when I click it there, it display the PHPMyadmin error page as in the following image https://i.imgur.com/p8HokOm.png

I finally realised phpMyadmin was not installed so I installed it after I updated mysql and it still shows the same problem, cannot access anything

This server had a very old mediawiki and php installation and we updated php to 7.4 and then had to revert back and downgrade to php 7.3 because mediawiki doesn't support php 7.4 so I wonder if that was the cause that broke phpmyadmin?

Would appreciate some help since I've been on thsi for hours now to no avail

change the port numbers under Config > Service and Port Settings?

close Apache2 before start XAMPP, the folder is maybe on : opt/lampp/htdocs/

You use wrong url. Use IP/phpmyadmin instead. Or any domain assigned to your VestaCp/phpmyadmin
Like example.com/phpmyadmin or 123.123.123.123/phpmyadmin
