title: place order error in magento
body: <p>After upgrading my magento installation to the latest (1.6.1.0), I noticed a popup error message at the final checkout stage (when pressing the "Place Order" button). The message says: "There was an error processing your order. Please contact us or try again later."</p>
  
  <p>Everytime I try to place an order, I get this error message.. How can I fix it?</p>
  
  <p>thanks in advance</p>
