You can get the two updated OAUth modules from
https://github.com/abraham/twitteroa...r/twitteroauth
Place them in includes\twitteroauth.
Also, in the vBulletin 2 Twitter: Thread To Twitter plugin, you will see four lines near the end as follows:
// if ($twitterApiLimitCheck->remaining_hits > 0)
// {
$twitter->post('statuses/update', array('status' => $tweet));
// }
Comment the three lines out as I have above.
Warning, I do not know PHP. I just guessed that this would work, and it does.
