Hi Hatami110, Since you re-install your wamp server probably your previous database are all gone, check you wp-config.php see your database name and go to your phpMyadmin. If all are still there then you can able to fix it by adding this line of code define(‘WP_ALLOW_REPAIR’, true); to your wp-config.php this will fixed the issue you have right now let me know if this solve your problem it will be my pleasure helping you guys
I agree @wpyogi but I advice that you should work your development site with xampp which is able run on a multi-platform operating system and also it is more lightier than wamp.
