I am having problem in displaying PayPal payment method in payment method section of onepage checkout in Magento.

I am using “PayPal Website Payments Standard“.

I have enabled this module from backend (System -> Configuration -> SALES -> Payment Methods -> PayPal Website Payments Standard).

I have also entered the Business Name and Business Account at “Website Payments Standard” (System -> Configuration -> SALES -> PayPal Accounts -> Website Payments Standard). I have set Sandbox Flag = Yes and Debug Flag = Yes. I am using Sandbox business name and account.

After doing all this, I think I should see the PayPal payment method option in my Checkout page on Payment methods section. But PayPal payment option is not displayed there.
