You can follow the same steps you would for a password reset, when accessing wp_users your username should display there. You don’t necessarily need to reset your password unless you use the username there with the password you remember and it doesn’t work.
I follow the steps but the problem still exist but there is a new Notice Notice: Function WP_Object_Cache::add was called incorrectly. Cache key must not be an empty string. Please see Debugging in WordPress for more information. (This message was added in version 6.1.0.) in /home/vol2_5/epizy.com/epiz_32772477/htdocs/wp-includes/functions.php on line 5835
I found the table wp_users on database empty , so I add a new ligne (new username and new password) , then I try to connect with them in my website but they said that the password is incorrect !!!
