title: Paypal error: Some required information is missing or incomplete
body: <p>I have been successfully testing my site for a few weeks now and just when I was ready to go live with it, I suddenly get this error:</p>
  
  <p>Some required information is missing or incomplete</p>
  
  <p>With no explanation as to what is missing! I have not changed anything - this was working yesterday. I have tried clearing cookies, using a different browser, turning off my computer, resetting my IP and trying a different computer, but nothing works!</p>
  
  <p>Our developer (in another conuntry) says that he can place orders just fine! I don't understand why he can but I cannot. </p>
  
  <p>What would have caused this sudden error?  I use a custom cart on my site which sends this (as an example) to PayPal (and uses auto return to process things after payment is made):</p>
