title: The type initializer for 'PayPal.Manager.ConfigManager' threw an exception >Paypal SetExpressCheckout
body: <p>for some reason I am getting an error "cannot read config file" when trying to set the SetExpressCheckout, I have copied across the web config settings, but for some reason I cannot read them, the error isn't very helpful other than what I have mentioned.</p>
  
  <p>I am using mvc4, and to be honest I have had a problem reading the web.config in the past..</p>
  
  <p>any suggestions would be much appreciated.</p>
