Locked out of updated blog

My site, sixredheads.com, is a few years old (2005) and I keep it updated frequently. Last week I ran the latest wordpress version update, which I’ve done on 13 other sites with no issues. On my site however, it will not allow me to log in.

I have attempted to reset the password using the email link. I get the emails, the new password and link, and it does not let me in.

I’ve changed my admin email manually in my server panel, also with no effect.

I’ve run emergency.php with no effect.

I’ve run another, fresh, update, with no effect.

I found an MD5 plugin but without access to the dashboard to activate it, I’ve not been able to use it.

Are there any other options to get into the site and dashboard?
