When I try to access my website, it throws error " Error establishing a database connection". I have checked my databases, it shows 0/unlimited. I have not deleted or recently changed anything in database. Please check and resolve. Thanks
Hi and welcome to the forum! Try to change your hosting account password from your Client Area, as it’s also said here:
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.
