wp-login/register

While on wordpress login page I click on register and it is still taking me to the default registration page my site.com/register/ even though I have membership plugin installed.

wp-login line 403 is set to

a href=”?php echo site_url(‘wp-login.php?action=register’, ‘login’:wink: ?>”><?php _e(‘Register’:wink: ?

If this is the line/file I need to make the changes on to redirect users to my membership registration page..

1. What changes exactly do I make on that line?

2. Do I just copy line 403 only to a new wp-login.php file?

3. Where exactly do I place my changes so a future wp upgrade won’t delete it?

If I am driving on the wrong side of the road, how exactly do I accomplish this?
