However, when you’re getting “One or more database tables are unavailable…” or one thing else however the notorious “EEDC” error, your database is corrupted and in die want of repairs.

Don’t fear one bit although, as repairing your WordPress database is simple peasy work. You may be achieved this in three easy steps. Firstly, find the wp-config.php file, which lives in your WordPress root listing. The root listing is the folder the place your WordPress site is put in.

outline('DB_NAME', 'database_name');

/** MySQL database username */
outline('DB_USER', 'database_user');

The particulars in the second pair of parentheses, the place now we have ‘database_name’, ‘database_user’, and so on, will not seem as proven in the code above. These particulars are particular to your website and host.

The 4 traces merely imply:
