I am having a similar problem: I try to email a user by clicking the green email icon from a user's profile and receive the error message
Sorry, the requested user does not exist.
This only happens if I click the email link from within a users profile. However, if I click the email link when viewing the full list of users, it works.
I compared the two links that the email icon points to and the difference seems to be that the link that works points to
while the link that doesn't work points to
http://mydomain.com/index.php/CAR/manag ... Profile?to
It's the "userProfile" bit of the URL that I need to change to make the link work.
I am assuming it's a coding error somewhere? Any idea how I can fix it in the code?
