Google analytics not working

[jerpint]

I have created and added my google analytics in the _config.yml file:

google_analytics: UA-********-*

I also have the url properly set in config. I built my site using:

JEKYLL_ENV=production bundle exec jekyll build

When I push my site on to production, google analytics registers nothing. Any ideas?

Also, as an aside, is it safe to share a google analytics code? I wasn't sure, so I put *s instead of the actual code.
