Google Analytics is sayng:No hits! Either your site is not receiving any sessions or it is not tagged correctly
<p>According to google analytic my site is not receiving hits. I have added the google analytic code in the head section of the site, in all the pages.</p>

<p>When I checked the site using Google Tag Assistant, it gave an error that "No HTTP response detected".  What does this mean? Is this the reason why my site is not receiving hits?</p>
