Hi ,

I have upgrade my site zen-cart 1.3 to 1.5 version. and I have used express checkout in my site.

Express checkout button , which is send cart detail to Paypal without user Login.

Now , I have getting problem with express checkout button which is not send cart order detail to the Paypal payment screen.

Here is the screen shot of my site express checkout button screen.



After click on checkout button it will redirect to Paypal screen as below , but not take cart item information with Paypal It is display blank in Paypal screen as below.



Problem occurred while customer was attempting checkout with PayPal Express Checkout button only.

Any one have solution for this issue..?
