BuddyPress.org

Hi everybody,

I installed Buddypress on my website and it works fine.
But when an user enters an incorrect password to login, the website redirect him in a error page (Http 500 internal server error), whose link is http://mysite/wp-login.php.
I want users to be warned that they have entered an incorrect password and have the possibility to insert the correct one.
Users login is done by a simple widget.
How can i solve this problem?

Thank you!
