On the login page of my app, I am now getting the following warning in the console log:
Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/.

What is this and what does it mean?

1) The app name is Sherakbar VIP
2)The login name is admin and the password is ravine, Although the error occurs before login.
3)It occurs when you navigate from the username field to the password field (turn on the console prior to navigation to see the warning).
The app is shared with support.
