Cannot login!

Hi there,

I can no longer sign into my own WP hosted on my website!

The username/password combination on wp-login.php is reportedly incorrect, and when I try to reset the password and fill in my email, I get:

There is no user registered with that email address.

The only username seemingly registered anymore is Admin, but I don’t seem to have the password for it…

How would I go about fixing this issue?

Thanks
