Hello
This message appears while saving changes.
"Authentication failed due to invalid authentication credentials or a missing Authorization header."

How can I solve this problem?

Not logging into PayPal, I think the problem is with this error message.

Since that extension gets credentials automatically, try using the 'disconnect' button and then running the connection process again using the most recent version of the extension.
