Post upgrade to 2.2.2 from 2.0.3 Superuser account doesn't work (2 replies)

Hi there,

I've just updated our server from 2.0.3 to 2.2.2, however, I now can't log in as the Superuser as I get the following frontend error message:
Error: Wrong Username and password combination.

Username and Password are stored in Lastpass so I know that they are correct and haven't changed.

I'm just wondering if there's an easy way to recover access (there are no other admin accounts on this installation.)
