Could you explain in more detail what you’re trying to do?
I posted this under PIMP YOUR PRESS I didn’t really have a problem but sure,
Okay the login on top is login from BuddyPress.
You can enter your login name and pass there and login without leaving the page.
You can click signup and it will take you to http://kiaspeed2.com/register which is themed.
When you enter the wrong password it takes you to this page http://kiaspeed2.com/wp-login.php which is not a them page. I want don’t want them to see that page.
Okay, this is more of a WordPress/BuddyPress issue really, but get a login theming plugin. You could redirect /wp-login.php to /bb-login.php, but that would most likely screw things up.
