What CSS was used for Comments here?

THANK you !!
Yes, it is Broken, but I have followed ALL the instructions on how to embed but for some reason(s) it seems I I am not getting it right.
Here is what my Embed looks like.


That configuration generates this code code.

<script type="text/javascript">
    if (window.location.pathname.indexOf('/p/') < 0) {
        DiscourseEmbed = {
            discourseUrl: 'https:/teachmeai.ogatutor.com/‘,
            discourseEmbedUrl: '{{url absolute="true"}}'
        };

        (function() {
            var d = document.createElement('script'); d.type = 'text/javascript'; d.async = true;
            d.src = DiscourseEmbed.discourseUrl + 'javascripts/embed.js';
            (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(d);
        })();
    }
</script>

Note: I left the Path Allowedlist empty because, when I enter anything there, the code will not even run
What could I be doing wrong?
Thanks
