Paypal Standard not set up correctly - Not redirecting, Email is not valid error

I don't know which configuration needs attention, Paypal or NopCommerce.  I wonder if you can help me.  I'm setting up my site for the first time and only have Paypal standard enabled for the payment option.  

I get to the CheckoutPaymentInfo.aspx page in the cart and see the "You will be redirected to PayPal site to complete the order." but when I click the next button, no redirect happens.  It just goes to the CheckoutConfirm.aspx page and says "Confirm your order" and an error gets thrown when clicking the "Confirm" button: "Email is not valid"

I know the configuration needs work, but where?  Here is all the info I figure you'll need; if you need more, I'll be happy to include:

That's OK. There's always a "Confirm Order" step.

Regarding email. It means that you entered wrong email address on billing or shipping address.

Thanks Andrei.  But the email is a valid email address.  

Do you have step-by-step instructions on how to set up Paypal Standard?  Maybe I'm missing something on that end?  I'm thinking that because it doesn't redirect to Paypal Standard after clicking Confirm.  Do I need to set up something intricate with Paypal?

I found the problem.  The email address has an extra space at the end.  You need to trim email addresses before you save the user account information or it will fail the shopping cart.  

That seems like a pretty big bug since it would cause lost revenue - people get frustrated and just leave the site not buying anything and you'll never know it.  All because of a data entry issue.

I agree. After clinching the sale, the customer walks away all pissed off and you lose both customer and sale!!

What version are you using? This bug was fixed long time ago.

Yeah, it's an old version.  1.40.  Ok, I'll upgrade.  Thanks.

Hi Andrei,

What is the process you'd recommend for upgrading 1.40 to 1.70?
