Actually I went applied the patch manually as it wouldn't work.
and so I got this message.

Fatal error: Call to undefined function tou_i18nstrings() in /home/connecte/public_html/drupal/sites/all/modules/terms_of_use/terms_of_use.module on line 158

Cheers

Thank you very much, but still not working at all.

Hi,

I've quickly updated this patch for 6.x-1.3.

I removed the two calls to filter_xss(tou_i18nstrings when getting the variables, which I think was causing the error.

I've also changed the check

if (user_access('administer users')) {
    return;
  }

to

  global $user;
  // Only present the terms of use pane on the checkout form if user is anonymous.
  if ($user->uid != 0) {
    return;
  }

Jason.
