I have setup the AMP plugin in WordPress but while going to see the AMP pages (Appearence->AMP), I saw an error "Non-existent changeset UUID".
Also there is message in console says, "Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://test.com') does not match the recipient window's origin ('https://test.ve.staging.wpengine.com')."
Please help me to resolved it out.
