Using the "K2 User" module (on K2 Version 2.5.5), when a user tries to log in and enters the wrong log in details Joomla takes the user to a HTTP Error 500 Internal server error page.

I would like to have it display some message that he/she has entered the wrong username/password.

Does anyone know a solution for this? Thanks!!

I turned on "Debug System" and it says:

Call stack
# Function Location
1 JSite->dispatch() /Library/WebServer/Documents/index.php:42
2 JError::raiseError() /Library/WebServer/Documents/includes/application.php:198
3 JError::raise() /Library/WebServer/Documents/libraries/joomla/error/error.php:251

Set the folder
logs
and file error.php
to CHMOD 777
