One or more database tables are unavailable. The database may need to be repaire

Hi,

I get this message: One or more database tables are unavailable. The database may need to be repaired.

I click on the link and get this message:

To allow use of this page to automatically repair database problems, please add the following line to your wp-config.php file. Once this line is added to your config, reload this page.

define('WP_ALLOW_REPAIR', true);

I’ve added this line of code, reload the page (and deleted my browser cache) but nothing happens.

What can I do?

The page I need help with: [log in to see the link]
