Problem with username registration plugin

[malmazan]

Man, is this driving me insane ...

Since the plugin was not working, i though i would try changing class_dm_user.php file instead.

So i replaced:

PHP Code:

So i replaced:        $username = trim(preg_replace('#\s+#si', ' ', strip_blank_ascii($username, ' '))); 


with

PHP Code:

        $username = ucwords(strtolower(trim(preg_replace('#\s+#si', ' ', strip_blank_ascii($username, ' '))))); 


(ie. add ucwords(strtolower to teh existing line)
And still no results!!

Can anyone shed some light on this?

?I am begging you!
