Reset admin password 4.3.1

I have not logged into my WordPress site using my admin account for a long time – I generally just use my editor account.

When I tried to login using my admin account today, it failed. When I tried to reset via email, it failed. I have also confirmed the email, and attempted updating it in SQL but it still fails.

I attempted resetting the password using:
– functions.php
– SQL
– creating a new admin user (using SQL)

All attempts failed.

I tried setting the password for the admin user the same as the editor users password in the database, as I know the editor account works, but that didn’t work either.

If anyone can help me regain admin access to my WordPress site I would greatly appreciate it.

Thanks
