Invalid Security Token on "Mark All Read"
 

The following code in forumdisplay.php is causing an Invalid Security Token error message on mobile browsers (IE Mobile on Windows Mobile 6.1)

Code:

// Prevent CSRF. See #32785
$vbulletin->input->clean_array_gpc('r', array(
'markreadhash' => TYPE_STR,
));
if (!verify_security_token($vbulletin->GPC['markreadhash'], $vbulletin->userinfo['securitytoken_raw']))
{
eval(standard_error(fetch_error('security_token_in valid', $vbulletin->options['contactuslink'])));
}

The full code in that area is:

Code:
// ############################### start mark forums read ###############################
if ($_REQUEST['do'] == 'markread')
{
// Prevent CSRF. See #32785
$vbulletin->input->clean_array_gpc('r', array(
'markreadhash' => TYPE_STR,
));
if (!verify_security_token($vbulletin->GPC['markreadhash'], $vbulletin->userinfo['securitytoken_raw']))
{
eval(standard_error(fetch_error('security_token_in valid', $vbulletin->options['contactuslink'])));
}
require_once(DIR . '/includes/functions_misc.php');
$mark_read_result = mark_forums_read($foruminfo['forumid']);
$vbulletin->url = $mark_read_result['url'];
eval(print_standard_redirect($mark_read_result['phrase']));
}
// Don't allow access to anything below if an invalid $forumid was specified
if (!$foruminfo['forumid'])
{
eval(standard_error(fetch_error('invalidid', $vbphrase['forum'], $vbulletin->options['contactuslink'])));
}
Why is this new Security Token feature for marking the forums read not working on this mobile browser???

Any ideas?
