Friends,
We were told that a few of CNP users are facing login issues and broken thumbnails at times.
We use to face this issue sometime ago due to excessive access to the website and limited resources. Currently some of us who use good broadband/4G connections are not seeing this issue anymore. If you still have this issue then it may be due to stale cache and cookies. We request you to clear the cache and cookies of the browser you use.
Here is a link which explains how to clear cookies/cache on different browsers.
Thank you!
