Hi Everyone,
Currently we using opencart to develop our e-commerce, we installed Paypal Express checkout as our payment option, and we integrate with sandbox account tried it on local, it's working fine, but after we upload to server, The Paypal Express checkout not working anymore, Does anyone met this problem before.
Scenario:
In Local
Go to checkout Page, fill in deliver address and select payment method "Paypal Express Checkout", and click checkout. System redirect me to Paypal page, login to my Paypal account and make payment. Once done system will redirect me back to my e-commerce website and show successfully.
In Server
Go to checkout Page, fill in deliver address and select payment method "Paypal Express Checkout", and click checkout. System not redirect me to paypal page, keep redirect back to current stage.
Error log from system
