Uncaught ReferenceError: jQuery is not defined

Something is calling jQuery incorrectly.

There’s still something wrong with that facebook pixel:

fbevents.js:23 [Facebook Pixel] - Call to "fbq('init', '115661712475335', []);" with parameter "user_data" has an invalid value of "[]"

Also, this is still an issue — the block with

<script>
  fbq('track', 'ViewContent');
</script>

in this bit of code from that plugin:

<!-- Facebook Pixel Code -->
<script>
  !function(f,b,e,v,n,t,s)
  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
  n.callMethod.apply(n,arguments):n.queue.push(arguments)};
  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
  n.queue=[];t=b.createElement(e);t.async=!0;
  t.src=v;s=b.getElementsByTagName(e)[0];
  s.parentNode.insertBefore(t,s)}(window, document,'script',
  'https://connect.facebook.net/en_US/fbevents.js');
  fbq('init', '115661712475335');
  fbq('track', 'PageView');
<script>
  fbq('track', 'ViewContent');
</script>
</script>

I recommend asking at https://ww.wp.xz.cn/support/plugin/official-facebook-pixel/#new-post so the plugin’s developers and support community can help you with this.

Is that the cause of the jQuery error? I’m not sure. I can’t keep checking your site for each plugin. You need to do this. DISABLE ALL PLUGINS and see if the jQuery error goes away. If so, then enable them one at a time until the error returns, and you’ve found the culprit. If not, then it’s an issue with your theme.

You have not cleared your cache. W3 Total Cache is still loaded.

At this point, we’ve reached the limits of what most in the community here are willing to offer in their spare time (everyone here is a volunteer). You should consider hiring someone so that you can give them direct access to the site for a far more efficient fix than we can provide here.

Please try https://jobs.wordpress.net/ or https://jetpack.pro/ and do not accept any hire offers posted to these forums.

We will keep this thread open, unless it veers too far off course, in case someone from the community is willing to provide further help here for free.
