CB Registration Auton Login and Redirect

Hi;

Has anyone been able to get the CB registration to auto-login then redirect (to home page for me) ?

All is workinging nicely with no extra code but after form submission i get a blank page and of course am not logged in yet.

... any tips on how to begin? I tried after submit php but no go so far wih my own attempts.

ANY help greatly appreciated.

Thanks, FRank
