One Disqus comments for all urls

Question

I have Disqus comments on this page but comments don't show up when the page have query string like when someone visit from twitter or buffer (it have query string):

?utm_source=buffer&utm_campaign=Buffer&utm_content=bufferc1465&utm_medium=twitter

I have this in js:

var disqus_shortname = 'jmicro';

and there is no window.location anywere. How can I make Disqus comments work?

Answer 1

Found it (disqus help respond on twitter) you need to set disqus_identifier variable, more info here.
