1. Firefox: One-two days ago content is displayed
2. Internet Explorer doesn't display the latest blog post
SOLUTION: Clearing the Temporary Internet Files
In Internet Explorer, Go to Tools > Internet Options > Browsing History Delete Button > Temporary Internet Files Delete files Button
This will delete all the copies of webpages, images and other media that are saved for faster loading and viewing of web pages.
For Firefox, Go to Tools > Clear Private Data or just press CTRL+SHIFT and DEL button to open the window. Check "Offline Website Data" and press the "Clear Private Data Now" Button
This solves my problem in posting new blog entries and viewing the recent webpages.
