Order Status is Pending after Paypal Payment I created an order with weekly or monthly subscription. User can purchase the subscription only through paypal. 

If a user purchase the subscription he redirected to paypal site. After successfully payment the order is created. But the order status showing pending. It should be completed.

Recurring Module : UC Recurring Payments and Subscriptions

Payment Method - Paypal

(Edit) Problem was in Sandbox paypal Account. Api Credential (Password and Signature) was not there. I changed the merchant account Api Credential.

After changed the api credential same problem occured with changed account. What to do?
Ubercart does not make orders completed on it's own. It seems to be a well known problem, already discussed on stackoverflow and on ubercart.org. It seems manually setting up Conditional Actions is a must in most cases.
