Not getting redirected from PayPal Standard to order completion page

Searched the forum but couldn't find this particular problem.

Using nop 2.5 and using PayPal Standard as my only payment option. Tested good using PayPal's sandbox. In production, using real PayPal accounts and a test product, the payment goes through, but when PayPal redirects back to my store, it opens up the store's home page (www.national-language.com/store/). When I tested in the sandbox, the order completion page was displayed after the PayPal transaction was completed. This isn't getting displayed in production. Thanks for any ideas and solutions.

Here are my settings in PayPal:

IPN handler:
http://www.national-language.com/store/Plugins/PaymentPayPalStandard/IPNHandler

PDT return URL:
http://www.national-language.com/store/Plugins/PaymentPayPalStandard/PDTHandler

PayPal Standard Configuration:

Use Sandbox: (deselected)
Business Email: (my email)
PDT Identity Token: (my token)
PDT. Validate order total: (selected)
Additional fee: 0.0000
Pass product names and order totals to PayPal: (selected)
Enable IPN (Instant Payment Notification): (selected)
IPN Handler: (blank, default)

I have the same problem.  Did you work this out?

I never found a fix for it. The payment process started working magically on its own, so I didn't investigate further. It may have had something to do with reuploading the entire application to my web server, but that's just a guess.

Thanks for your interest.  Yeah,  I just went thru the steps again and it worked.  I must have had a typo somewhere.................
