Invalid Login while trying to Login

I have setup new production & server and enabled dns based multitenancy. I setup 1st site & was able to login properly & created few users & also entered some data. I was able to login through newly created users also. After that I created 2nd Site & was able to login properly .

Now when I try to login into 1st site I am unable to login through Administrator or User. It is giving error message “Invalid Login - Try Again” . My 2nd Site is working properly and able to login.


Issue solved. It was browser cache issue. In another PC it was working properly.
