First off, I'd like to thank anyone who replies in advance--
I am using vBulletin 3.7 (old, I know...), and I am trying to add a plugin that includes the variable $post['postid']. However, it doesn't seem to work. The hook location is 'postbit_display_start'.
I see no need to post more information; the problem is very small, and hopefully very simple.
Try to use postbit_display_complete as the hook location. And use this plugin code on your local installation
To see what are within $post.
