title: Uncaught ReferenceError: _gaq is not defined - Switch to universal analytics
body: <p>I recently updated to universal analytics and now push event data to the datalayer, rather than using the old _gaq. I've gone through my code and removed all traces of _gaq, however, when events are firing i'm getting the following error message:</p>
  
  <p><strong>Uncaught ReferenceError: _gaq is not defined</strong></p>
  
  <p>It appears that there are still some references inside the following file:</p>
  
  <p><strong><a href="http://www.googletagmanager.com/gtm.js" rel="nofollow noreferrer">http://www.googletagmanager.com/gtm.js</a></strong></p>
  
  <p>Is it possible to refresh this script so that it removes any references to _gaq?</p>
  
  <p>Any help would be much appreciated </p>
