Can not log in PLUS "your host may have disabled the mail() function"

I see that people have been asking about this problem for years. Please note, I can not use any of the solutions that require logging in, because I can not log in. I’m also staying away from the solutions that warn they’re only for PHP experts.

I believe I know my password for logging in to my blog. WordPress thinks I don’t. When I try to get a new password, WordPress will not mail me a new password because, “your host may have disabled the mail() function.”

I found one solution that said I could change the password by FTP in themes.ftp. After the first line

<?php

I added

wp_set_password( ‘password’, 1 );

Then the instructions said to add a new password. ***But where?*** I tried replacing the word password between the single quotes, but that didn’t work. Do I remove the single quotes? Do I put the password in a line below? Please be explicit.

thanks
