Exception on login

[Elday12]

When I login using Google auth, I get the following exception :

Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.

If I replace

decodeURIComponent(escape(window.atob( str )))

by

(new Buffer(str, 'base64')).toString('utf8')

it fixes the issue.

Thank you !
