Do you know why this error happens?
It is a general problem that comes when WordPress is unable to find proper access to the database.
And now I’m going to walk you through the steps to solve it so your site will be running efficiently once more.
Step 1: Log into cPanel
To solve this problem first sign into your cPanel. After logging into the control panel you will be directed to the cPanel, now click on File Manager.

Step 2: Check Database Details in wp-config.php
In the wp-config.php file, you will find.
- Database name
- Username
- Password
In other words, if any of this information is incorrect or doesn’t match what is stored in actual database credentials WordPress will not be able to connect and the error will be coming.
Time to explain…
Step 3: Check Your Database info on cPanel
To ensure the credentials in wp-config.php are correct, follow these steps:
1. Return to the cPanel and look for the Databases link.
2. After clicking on it you can see your database name,
Username and password.
3. All this has to be compared with the one in the file known as wp-config.php.
4. If the database name, username, or password doesn’t match, then change it in the WP-CONFIG.PHP file. Just you can copy and paste it into the wp-config.php file in the exact place.
If required, reset the database password in the backend from cPanel after that update the same password in wp-config.php and finally save the changes.
Jump to…
Step 4: Refresh the Site
After you update your credentials, save the changes in the wp-config.php file and refresh your site. If the database information was the problem then your site should open perfectly as it is right now.
Step 5: Fix 404 Errors in WordPress Dashboard
There is no known method to prevent 404 errors from happening.
So the next best thing to do is to fix those errors in the WordPress dashboard.
At other times after rectifying the database connection error you can still see some 404 errors on the sites. To resolve this:
1. First, you need to log into your WordPress dashboard.
2. Click on Settings in the WordPress Administration toolbar, then click on Permalinks.
3. Just click on Save Changes leaving all the options in default settings.
By doing this it will replace the current permalink structure and should eliminate all the 404 errors.
