title: Google Tags not fire on any of the event for a wordpress site installed in subdirectory of a domain
body: <p>I have google tag manager installed on my main site and everything works well. Now I create another WordPress site in the subdirectory of my domain. (By using WordPress multisite function) I added the same google tag manager to my new site. However, when I check it with the preview function of google tag manager, I find <strong>none of the tags</strong> fire on any of the events. </p>
  
  <p>The firing Triggers are all successful, but the tag is not successfully fired. I can't see the "Firing Status: success" link in the properties section. Also, for the link clicking event, I can't see the google analytics settings line, and the tag label line is "undefined".</p>
  
  <p>The site is:  <a href="https://www.canfitpro.com/convention-2020/" rel="nofollow noreferrer">https://www.canfitpro.com/convention-2020/</a></p>
  
  <p><a href="https://i.stack.imgur.com/vVClF.png" rel="nofollow noreferrer">tag not fire</a></p>
  
  <p>I'm wondering if anyone knows what happened and how I can fix this?</p>
  
  <p>Thank you!!</p>
