If the message “The Reset password token attribute is invalid” appears when you are setting the new password after clicking on the email you received when you clicked on “Forgot your password?”, it means that you must have clicked more than once on the button and as such must have received more than 1 email.
In this case, only the most recent email link is valid. You should discard the oldest emails and use the link of the most recent.
If you still cannot overcome the problem send us a request for help.
