    Which payment gateway are you using? And version of PayPal if you are using PayPal.

    Are your API credentials/etc set correctly? Double check them.

    Hi! thank you very much!

    I have changed it form sandbox/testing to live/production and it seems that work now… what is the difference between them? i was using sandbox/testing before updating but i dont know what they mean.

    That will do it too.

    Sandbox/testing requires a different PayPal account setup at http://sandbox.paypal.com and is for … testing. The live account is your actual PayPal account for real money.

    Enjoy

    Thank you, boss! it may be changed when i update the plugin or the WP version.

    Thank you so much! 😉
