Jessie Abernathy Posted October 10, 2018 Share Posted October 10, 2018 I am getting this error in my dashboard PayPal Balance: Error: Security header is not valid I thought that I had entered my Paypal credentials correctly and everything was working fine... But I guess not 🙂 Shouldn't I be able to see my paypal balance right there? (see attached screenshots) 0 Quote Link to comment Share on other sites More sharing options...

Jessie Abernathy Posted October 11, 2018 Author Share Posted October 11, 2018 I have since solved this issue.. it wasn't even in the Payment Gateway settings.. it was in the Addon Module for the Transaction Lookup ID (LOL!) I had the wrong credentials entered in there, I got the correct credentials now and i can see my paypal balance (which is $0.00 but still!)  Thanks for your help 🙂 1 Quote Link to comment Share on other sites More sharing options...
