ACP > Users > admin account > User Essentials When I try to change my username there I get the error below; My password is correct, because it allowed me to log into the ACP. The error is not resolved by entering my password into the password field on that "User Essentials" form. Another small issue is that when I enter my password there, it actually shows my password, e.g. it shows 'pass' and not '****'. What could be causing this error and how can I change my username? Thanks!
