When someone puts the item in their cart it does not come out of inventory so it allows multiple people to have the same item in their cart and then when one person checks out the other people that has that same item cannot check out. It gives them and "internal server error" and then it seems like their cart doesn't work again even if they remove the item. I hope there is a fix for this because people were not happy.

The fix will be included in next release. In the mean time you can do this: In the file components/com_hikashop/controllers/checkout.php, after the line: $done = $cartClass->loadFullCart(true); add the code: if(empty($done->products)){ $app =& JFactory::getApplication(); $app->redirect( $this->redirect_url, JText::_('CART_EMPTY')); } Then, in the file administrator/components/com_hikashop/classes/cart.php, you need to change the lines: $notUsable[$k]=0; by: $notUsable[$product->product_id]=0; You should have it 4 times. That solves the problem on our end.
