Open your cPanel and head over to the MySQL database, there will be an option for the users. Make sure you have allocated all the permissions to the users. If you haven’t done it already, you need to make sure that you create a MySQL database and give all the permissions to the person.

One of the best ways to solve any error in WordPress is to roll back the changes that you recently made. If you recently installed a plugin, then you need to deactivate it.

If you don’t have the access to wp-admin then how will do it?

Well, the answer is simple. Open your file manager and open the WordPress directory. Head over to the wp-content folder. When you go there, you will have to select the plugins folder. Inside the plugin folder, find the plugin that you want to deactivate. Once you find it, just rename the plugin and that’s it.

First, you need to check that your database is present or not. So, head over to the MySQL database from the cPanel and then see whether the database is there or not.

If it’s there, you need to repair it. You can add the following line in the Wp-config.php file. See the above steps to know the path.

define('WP_ALLOW_REPAIR', true);
