Error 15008 when is used a discount

-- Joomla version -- : 3.3.4
-- PHP version -- : 5.3.21
-- Browser(s) name and version -- : Chrome
-- Error-message(debug-mod must be tuned on) -- : Error 15008: This transaction has been completed, but the total of items in the cart did not match the total of all items.

I receive the following error when try to use a discount with Paypal Pro payment "Error 15008: This transaction has been completed, but the total of items in the cart did not match the total of all items."

Hi,

This should not happen with the 2.3.3 as we actually added a fix in the 2.3.2 for that error message.
Could you turn on the "debug" option of the PayPal Pro plugin and try again ? What debug data do you get displayed (you can remove the sensitive data in the debug before sending it) ?
