在php博客网站上实现disqus

I have this code to include in my php website but I keep getting this error: We were unable to load Disqus. If you are a moderator please see our troubleshooting guide. I have left trusted domains field empty in disqus dashboard to allow development on localhost. The id is specific to each post.

<script type="text/javascript">
                var disqus_config = function () {
                var id = <?php echo $_GET['id']; ?>;
                this.page.url = 'localhost/blog/viewimage.php?id='+id;
                this.page.identifier = id;
                };
                (function() { // DON'T EDIT BELOW THIS LINE
                    var d = document, s = d.createElement('script');
                    s.src = 'https://ashexcreations.disqus.com/embed.js';
                    s.setAttribute('data-timestamp', +new Date());
                    (d.head || d.body).appendChild(s);
                })();
            </script>
