[Plugin: WP User Frontend] some bugs ?

hello..

downloaded your plugin and installed it. thought it was the perfect solution for my project but after testing found some things i cant explain by myself.

1. a click on the (user([wpuf-edit-users])) edit button …/?action=edit&user_id=5&_wpnonce=3af729ff77 .. should do exactly what ? it gives me a blank wp page.
2. if i add a user manually, the user is not able to login … wrong password.
2a. the link in the email … /wp-admin ??? i think this should go to the plugindashboard page.

need help !

thanks
aleccs
