Checking for $type == 'thread' will allow any characters in reply titles, but the OP does specifically say "thread titles", so maybe that's OK.

Gripi, sorry for any problems this may have caused on your forum.

YA ITS IF NOT IIF

PHP Code:

if (!preg_match('/^[A-Za-z0-9\s]+$/', $post['title']) AND $type == 'thread')
    $errors[] = "Only letters, number, and spaces are allowed in title."; 


For newthread_post_start hook we need to modify the code to this

PHP Code:

if (!preg_match('/^[A-Za-z0-9\s]+$/', $vbulletin->GPC[subject]))
    standard_error("Only letters, number, and spaces are allowed in title.");
