Jelenaskopje. OK download the wp-config.php file, add the string
define('WP_ALLOW_REPAIR', true);
and then upload the new wp-config.php file overwriting the one that's there already.
Return to the browser page where you got the message to amend the file.
Then you click on something (sorry I can't remember what) and you get 2 buttons. Click the first one. I think it says Repair.
This is not obvious. I only discovered this button after returning 3 times to the browser page.
You then get a screen that shows the problem. It suggests you enter the information into a support forum. I didn't need to do this really.
Just sit tight and wait. For me it was repaired.
Finally you get a message asking you to delete the string
define('WP_ALLOW_REPAIR', true);
from the wp-config.php file. So do that and upload again. That's just for security.
Hope this works for you.
