Disqus "Show Comments" Button Stopped Working

I have a website that uses Disqus for comments. I use a button to hide the comments. The user must click the "2 Comments" button to see the comments:

For blog posts with Zero comments, Disqus loads.

If I try to click a button on a site with comments, nothing happens.

For example - try to click the "2 comments" button. https://john.soban.ski/m30-linux.html#disqus_thread

I use the following code:

 <script type="text/javascript">
                    var disqus = 'freshlex';
                    var disqus_shortname = 'freshlex';
                    var disqus_identifier = '/m30-linux.html';
                    var disqus_url = 'https://john.soban.ski/m30-linux.html';
                </script>
                <noscript>Please enable JavaScript to view the comments.</noscript>
                <section class="post-comments">
                        <a id="show-disqus" class="post-comments-activate" data-disqus-identifier="/m30-linux.html" >Show Comments</a>
                    <div id="disqus_thread"></div>
                </section>

and

<script type="text/javascript">
    var disqus_shortname = 'freshlex';
    (function () {
        var s = document.createElement('script'); s.async = true;
        s.type = 'text/javascript';
        s.src = '//' + disqus_shortname + '.disqus.com/count.js';
        (document.getElementsByTagName('HEAD')[0] || document.getElementsByTagName('BODY')[0]).appendChild(s);
    }());
</script>

For those of you who have a similar "button doesn't work issue:"

Go to Chrome's Developer tools, look for a red triangle, click it and read the issue

I have a theme that calls highlight.js. I did not load highlight.js and that killed all the following scripts, including my Disqus script.

I needed to add the CDN reference to my web page HTML.

So I added:

  <script src="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/10.7.3/highlight.min.js"></script>

And that fixed it.
