Cannot sign in or register new user

I just installed CS on my local machine. When I go to http://localhost/cs (the default page) and try to Sign In, after entering my username and password, and clicking Sign In, the page seems to just refresh but the form doesn't get submitted. My username and password gets cleared but NOTHING HAPPENS.

The same thing happens when I try to Join Our Community. It seems like the whole application is just not responding to form submissions.

This only happens in IE (6.0). It works fine in Firefox. I've tried deleting my cache and cookies, and "Checking for new versions of the webpage at every visit" (IE option) but all to no avail. What could be wrong?

Thanks.

Hey everyone, I was going to test CS 2.1 with the service pack.

After installation I encountered the same problem.
I cannot use the admin account to login.
The page is refreshed, however there are not extra buttons on the main nav and the sign in link still remains.
What can be the problem???

Normally both of the issues mentioned here are due to cookies and cache so please be sure you clear them both and restart the browser.

When i deploy CS2.1 in my local computer it is successful. But when I deploy it on server then the same happen to me. I can not login as admin user with correct password. Why ???

Please check this threads, may be you can find solution for your problem
