WordPress - Error establishing a database connection

My website https://domt.ml/ can’t connect to database! What’s happening?

Account: epiz_21685482

Error: Error establishing a database connection

All my data in wp-config.php it’s 100% correct!

Could someone check please?

I did not change wp-config.php and DB from the beginning, But now in Vista Panel - MySQL Databases there are different DB name, DB user name and server.

Could someone from Admins check this please?

Problem Solved


If you cannot connect to the database by going to phpMyAdmin, then you know it is something with server. It does not necessarily means that MySQL server is down. It could mean that your user does not have sufficient permission.

Warning: Be very careful using PHPMyAdmin, since you’ll be dealing directly with your site’s database

when I go to https://domt.ml/wp-admin/
this is show up:

Can’t select database
We were able to connect to the database server (which means your username and password is okay) but not able to select the epiz_21632048_w946 database.
Are you sure it exists?
Does the user 21632048_2 have permission to use the epiz_21632048_w946 database?
On some systems the name of your database is prefixed with your username, so it would be like username_epiz_21632048_w946. Could that be the problem?
