Analytics failing to report

Hi..

I've set up Analytics and followed installation procedures.. but it still wont catch and show the slightest tiny little info..
I'm getting an error..

"The [[i]domain[/i]] does not accept hits. Either your site does not receive any sessions, or it is not tagged properly.
Google Tag Assistant registrations allow you to verify that your site is properly tagged."

Im almost sure i've installed it right.. and also used this tag assistant but.. still nothing..
Something else needs to be added..?

Would be nice to see what all people are doing on the site..

Install Analytics debugger for Chrome and make sure that events are being sent
