Disqus same comments on all posts

Hey all,

The Disqus comments appear on all posts. How can I see if the page identifier is different from each comment?

My URL : noncodeur.com
Ghost version 4.5.0
The code (used the official tutorial):

 {{#if post.access}}
    <div class="comment container small">
    <div id="disqus_thread"></div>
        var disqus_config = function () {
            this.page.url = "{{url absolute="true"}}";
            this.page.identifier = "ghost-{{comment_id}}"
        (function() {
        var d = document, s = d.createElement('script');
        s.src = 'https://noncodeur.disqus.com/embed.js';
        s.setAttribute('data-timestamp', +new Date());
        (d.head || d.body).appendChild(s);
