    I’m testing my payment settings using the GoCardless plugin (which is downloaded and installed with licence key) and when I tried to pay a test invoice it brought back the error Error: API call failed:Invalid ‘Authorization’ header.

    What do I need to do to fix this please?

    Additional point that might help: even though I have activated my plugin and entered the licence key, I still have a message below the plugin saying This plugin requires a valid licence key to enable automatic updates. Not sure why.
