I am using WooCommerce PayPal Checkout Gateway and keep getting an API error after entering API credentials...I have entered them several times exactly as they ar created by the PayPal system. I am using Pay Pal checkout and manually entering API username, password and signature that was generated by PayPal. After entering the API data, then saving changes I get this message: Error: The API credentials you provided are not valid. Please double-check that you entered them correctly and try again. Has anyone else seen this....I have asked PayPal to chack on it as well. Thanks in advance for any help.
