  1. ensure that your old includes/classes/order.php file gets over-written by the new one (sometimes FTP tools don't over-write files that are already there)
  2. check that you have your stock settings configured both to check stock and to prevent checkout if its too low (Admin > Configuration > Stock Settings)
  3. don't leave any backups sitting around in your classes folder (sometimes FTP tools create these automatically)
Right, I've deleted all the SBA multiadd files and uploaded them again. I used winmerge to check the contents of each file against clean Zen files. The only thing I haven't done is touch the database.

And - it's still not working. Checkout works normally for stock items that don't use attributes, but any attribute items will checkout regardless of stock levels. The warning appears on the shopping cart page but it still lets you checkout.

Am I just going to have to live with it!?
