Did you try something like:

PHP Code:

$vbulletin->url = 'index.php?' . $vbulletin->session->vars['sessionurl'];
eval(print_standard_redirect("Invalid Thread", false)); 


You can also use a phrase instead of text (see function print_standard_redirect() in includes/functions.php).

ETA: sorry, I just reread your post and noticed the "after a few seconds" part, so maybe this doesn't help. (But maybe that's what the "forceredirect" parameter of print_standard_redirect() is for?).
