Unable to see posts on older published blog posts

[prashantkaria]

I have wordpress site and there are several posts there. I have installed disqus plugin and I am able to see disqus widget on recent posts but it's not showing on older blog posts. If I try to change publish date of older blog then it's showing disqus widget.

So is there any limitation to show disqus widget on posts which are posted after particular date or after installed disqus plugin date?

Here are two links (With comment section and without comment section)

Check on the Disqus settings if it closes comments on posts older than 28 days. I had this issue before.
