How to clear the cookies to solve this issue. You can either clear all cookies in your browser or cookies for the web site which you face problem. Here I am clearing cookies for my web site www.google.com, to get my GMail working fine.
Step – 1: Go to Google Chrome Tool menu (Spanner icon in top right corner) -> Options -> Under the Hood -> Content Settings… -> Cookies -> Show cookies and other site data…
Step – 2: Now you should get a window listing all domains which have stored cookies in your browser. Enter your web site which reports error in Search text box; on the fly your web pages will be filtered. In my case it is google.com. Now select Remove All button; which should clear all cookies for these web pages. The below screenshot shows this.
Step – 3: Now again go to your web site which reported error, you should get it done this time
