Disqus Commenting works on some posts and not on others.

For my Wordpress blog I use the plugin Disqus to generate comments. This has always worked fine until last week. For some reason, it disappeared on my last published post here: [login to view URL] It was there before, but approx after 24h it disappeared, hence the three comments. The Disqus plugin still works on my older blogposts, for example here: [login to view URL] Note : This is an urgent task and must be completed within 3-4 hours max. Bid only if you can fix this within this time & don't bid over $ 20 as thats the max budget for this job. Thanks,
