I can perform a login and logout.
But if I close the browser after a sucessful login (Or press ctrl+f5 to clear the chace) I get an error (In the console):
Failed to load resource: the server responded with a status of 400 ()
And the login button is grayed out.
I have node.js installed on a web server, and I am accessing the page from a client with an HTTPS connection
NOTE: I also tested it with a normal login (Not social)
