Hubspot integration help

I added those to the viewer_functions (see below), but the pages are still not loading. But if I remove those two new parameters from the URL, the page does load. 

    $removeFields  = array(
      'utm_source','utm_medium','utm_term','utm_content','utm_campaign',          // google utm names: http://www.google.com/support/googleanalytics/bin/answer.py?answer=55578
      'fb_source','fb_action_ids','fb_action_types','fb_ref','fb_aggregation_id', // facebook parameter names: https://developers.facebook.com/docs/technical-guides/opengraph/link-parameters/
      'action_object_map','action_type_map','action_ref_map',                     // additional facebook parameters
      '_hsenc','_hsmi',                     // additional hubspot parameters
    );
    foreach ($removeFields as $removeField) { $urlData = preg_replace("/&$removeField=[^&]*/", '', $urlData); }


Hold tight. I think there is a cache issue.

Was it a caching issue?
