Error establishing a database connection

[JxstErg1]

Hi and welcome to the forum! Try to change your hosting account password from your Client Area, as it’s also said here:

@Admin

Change the account password

Sometimes, if you change your password, the password isn’t processed correctly in the database server. You can force the password to be reset again by changing your hosting account password through the client area. Please make sure to use a different password initially, although you can change the password back to the original password you were using afterwards.

After changing the hosting account password, please wait for at least 15 minutes for the changes to go through the system. During this time, you may also want to clear cache and cookies to help make sure you will actually use the new password for phpMyAdmin.

After this, make sure that you have the right database username and password, which you can find on the “MySQL Databases” section of your hosting account dashboard on the Client Area, on your wp-config.php file.
