I recently configured a Magento based site(CE-1.9.2.4) with Paypal with client's Business Paypal account credentials.
Now when I add product to cart and provide the "Estimate Shipping" values in cart page, I get below error:
{"http_status_code":400,"http_status_message":"Bad Request","internal_message":"Bad format: merchant.id"}
Is this error related to Paypal, but I passed credentials correctly into Magento Admin and it shows no configuration error in there.
Anyone please help me out here.
