[Plugin: WP Google Plus Connect] Fatal Error Invalid Grant

Fatal error: Uncaught exception ‘apiAuthException’ with message ‘Error fetching OAuth2 access token, message: ‘invalid_grant” in /public_html/wp-content/plugins/wp-google-plus-connect/src/auth/apiOAuth2.php:84

I’m guessing this is the reason why it may not be working using v1.0.2
