 * Hello,
 * 1. It’s hard to tell why there is that error related to admin-ajax.php. We need
   to use admin-ajax in order to avoid cache plugins when we send Facebook CAPI 
   event. You can disable server-side events and test again.
 * 2. Again, hard to tell why it happens without being able to investigate this 
   locally. I assume there is something related to the theme you’re using. Can you
   test with a different theme?

 * Hello,
 * Thanks for the quick feedback. I really appreciate your efforts for this plugin.
 * I have tried both of your suggestions.
 * 1. Yes, disabling server-side events resolve the issue.
    2. No, the error doesn’t
   go away even I tried switching to WP TwentyTwenty Theme.
 * Is there any plugin file to exclude from caching to resolve the issue? Don’t 
   know I am a bit non-technie.

 * Please download the system report file from our plugin’s left-side menu and send
   it to us on our website.
 * It would also help if you can send the PHP error report logs, and a link where
   we can check the problems.
