Hi Nithin,
From my end, I can see the articles, however, I can also see some issues from your site which may be causing it not appear from yours: https://share.getcloudapp.com/2NumrJY1
Can you try clearing your browser’s cache first?
If that doesn’t work, as a first course of debugging and to check if a third party plugin is causing this, can you try doing #1 here?: https://docs.generatepress.com/article/debugging-tips/
It would be good to take a backup before doing so.
Kindly let us know how it goes.
