[P3R3]

We put together a fix for the user issue. There was an var mapfp that was not being set.

We changed the Map FB User to:

if (!empty($_POST['fbuid']))
{
	require_once('./includes/facebook/facebook.php');

	if ($vbulletin->facebook == null)
		$vbulletin->facebook = new Facebook($vbulletin->options['fbconnect_apikey'], $vbulletin->options['fbconnect_secret']);
		
	$fbuid = intval($vbulletin->facebook->get_loggedin_user());

	if ($fbuid > 0 && intval($_POST['fbuid']) == $fbuid)
	{
		//map fbuser to vbuser
		$vbulletin->db->query_write("
			INSERT IGNORE INTO " . TABLE_PREFIX . "fbuser
				(fbuid, userid)
			VALUES
				(" . $fbuid . ", " . intval($vbulletin->userinfo['userid']) . ")
		");
	}
}

Unfortunately there is another issue that the fb breaks all the AJAX functions. None of the ajax stuff works so I added the lines:

<script type="text/javascript">
<!--
// Main vBulletin Javascript Initialization
vBulletin_init();
//-->
</script>

back in to fix this

But there is an error with facebook which we cannot resolve that breaks the publish newsfeed functionality.
