Yes, I haven't enabled Google+ for my Google account (I'm not interested in this social network) . The fix doesn't work, I get a blank page with the message “Application error. We're sorry, an error occurred in application cloudnode.js”. Int the Firefox browser console, inside Security tab, the error message is: Blocked loading mixed active content "http://static.jgate.de/jquery-1.2.6.js".
In the Google Chrome console the error message is: Mixed Content: The page at 'https://cloudno.de/google/callback?code=4/erJmakPyo5MZUb1WfE5F7mgIVcXox90tIoTZ6d3Ns-I.gsjXMlKZZzwRoiIBeO6P2m_UI5I1mgI#' was loaded over HTTPS, but requested an insecure script 'http://static.jgate.de/jquery-1.2.6.js'. This request has been blocked; the content must be served over HTTPS.
