If the problem exists with that dashboard also then you can skip to the next step. You have done the eliminating of the problem as a potential cause,

Before starting this process, we need to edit the wp-config,php file for your site. There is another step to do that:

• The connection of your site with the FTP.

Step 2:

The running of the automatic database repair utility

After the adding of the code snippet given above you can now access the WordPress database repair tool on.

YOURDOMAIN.com/wp-admin/maint/repair.php

Just click on the repair database to start the tool. After the tool fixes all the problems, your site will be completely working again. Then you should return to your wp-config.php file and remove the code you have just added to the repair utility.

Potential Fix 2: (Go and check your database login credentials)

Before going on this step ensure that your database is not corrupted and also check that your database login credentials are working.

If somehow these data is not matching with the database credentials which you have created via your dashboard. Due to that WordPress will not be able to access your database. Just use notepad and write down this code.

</php

$link = mysql_connect(‘localhost’, ‘mysql_user’, ‘mysql_password’);

If (!$link) {

die(‘Could not connect: ‘ . mysql_error());

}

Echo (‘Connected successfully”;

Mysql_close($link);

?>

Just replace MySQL with mysql_password with the actual username and password. Then you have to upload that file to your website with the help of cPanel or by FTP.

YOURDOMAIN.com/databasecheck.php.

If “connected successfully” appears then your database credentials are working and just go to the next step.

But you have got a message saying access denied then there must be a problem with the database credentials.

Just go and create new database credentials for your WordPress site.

1. Go to my SQL database in cPanel:

Just keep in mind that your host is using the cPanel, just go and create the MySQL Database option in the dashboard.

2. Create a new user:

Just go to the MySQL and find the box to Add a New User, enter new username and password.

3. Just add a new user to the database:

After creating a new user, you can now go to the Add a User to a database option and add the user to your WordPress site database.

Use ALL PRIVILEGES on the next line.

4. Go and update the wp-congig.php file with the new database user:

Just to finish this process you have to go back to your site wp-config.php file and just update the DB_USER and the DB_PASSWORD.

Potential Fix 3 (Reupload the core WordPress files) :

If somehow all the above methods are not working to fix it then you should go with this one.

Just upload a fresh copy of  WordPress to your site. It will not affect your existing content, plugins, and themes.

Just update the version of WordPress by going to wordpess.org.

All you need to do now is to extract the zip file and delete the wp-content folder along with the wp-config-sample.php file.
