@Piyush Mahes Thanks for your post, there could be a few causes, if you followed the upgrade steps by uploading all the files and then navigating to /install to complete the upgrade there could be a fatal error occurring.

Could you try adding the following line to your configuration.php file:

$display_errors = true;	

Then try loading your admin area to check for any issues, please also try uploading a fresh copy of the /admin folder to see if this helps resolve the issue.
