You may use the following way, if inaccurate Login Credentials are responsible for the error establishing a database connection in WP.
Check With Your DB Login Credentials
Incorrect login credentials is a common reason for this error. Most of the time, it happens when users migrate to a new hosting provider, their old database credentials stop working. Apart from this, changing database names, resetting passwords can be other possible reasons.
The very first thing you need to do is, check your DB login credentials. The connection details of your site are located in the wp-config.php file and this file is located at the root of your WP site.
This file includes 4 important pieces of information that needs to be accurate for the successful connection.
You can access the wp-config.php file by accessing ‘File Manager’ via Cpanel of your web host. Now check all your values against those are on the server. Make sure all are accurate. If not, you need to change them.
To check the database name, you need to log into PHPMyAdmin, a feature in your CPanel dashboard. Here you can find your database name at the bottom. Next, compare database name against the DB_Name value. If you don’t find any database listed, then this problem might be with the host server.
Click on your DB name to see the names of tables in the database. Next, click on ‘Browse’ to find the name and URL and other settings of your website. If it is available there and matching with your wp-config entry, it means you have the right database. In case, if the URL is right but your wp-config file is inaccurate, you need to change it to match with the right database.
The next step is verifying the username and password. It can be done in two ways.
Make a small .php file to see whether you are able to connect to the database with the credentials from wp-configuration into a new text file type.
Next, save this file to your WP directory, you may give it a name: ‘connectiontest.php’. Next, type the file URL into the browser and try it. Now you will see either the connected successful message or unable to connect message. If you are not able to access your username and password then go to step 2.
If you can’t locate the username and password in the table, it is time to create a new username and password in the wp-options table. You can do this via MySQL databases.
Here you can simply create a new username and password. Click on ‘create user’ and then find ‘add a user to database’. Choose the username and password and then click ‘add’.
Don’t forget to update changes in the wp-config file as well. If the error still persists then the problem could be the DB_Host entry in wp-config. Most of the time, it could be because of local host’. Contact your hosting provider or use a tutorial offered by them. A good web host should be always available for your help.
Hopefully, this guide will help you resolve this error, hassle-free.
