If you are getting this error message and have used a 'special character' in your password, try it with a different one.
Some webforms will attempt to interpret special characters as system instruction codes - for example I would avoid using
? or
&.
Two adjacent special characters might also be problematic
This may
not be the reason for the form failing but it's probably worth experimenting.
