• added urls to oauth: http://{site_URL}/index.php?module=Google&view=List&operation=sync&sourcemodule=Calendar&service=GoogleCalendar http://{site_URL}/index.php?module=Google&view=List&operation=sync&sourcemodule=Contacts&service=GoogleContacts and http://{$site_URL}/index.php?module=Google&view=Authentificate&service=Google
• Setup of Account ends up with error as shown in screenshot. any idea?
