Twitter share not working

[maxxo]

There is some sort of shaded overlay on Twitter site and the content does not load. Unable to share via Twitter. Tried with Firefox and Chrome on an updated Win 10 pc.

I think that happens because you are not logged in and the login div that should show up doesn´t appear. In bundle.js, twitter url for sharing is incorrect. In that file it's defined as:
'twitter': 'https://twitter.com/intent/tweet/?text=' + text + '&url=' + url,
but i think it should be 'https://twitter.com/intent/tweet?text=' (no slash before ?)
I had this same problem in one of my projects. That's what i changed in my web and it worked.
