Magento background cannot be opened

After the local installation of Magento, sometimes ie can not login backstage, there is a blank, Firefox can, sometimes not. How to solve?

Workaround One:
This is a cookie problem, and using a non-IE core browser such as Firefox can solve this problem. Although the browser handles cookies in a similar manner, it is not 100% identical. Magento Other versions also have this problem.

The way to fix this problem in detail is to locate: app/code/core/mage/core/model/session/abstract/varien.php. Around 70 lines you can see similar:

Set Session cookie Params
Session_set_cookie_params (

' Domain ' = $cookie->getconfigdomain (),
' Secure ' = $cookie->issecure (),
' HttpOnly ' = $cookie->gethttponly ()

Comment out the back or delete.

Workaround Two:

No login on localhost

Change your IP address to login: For example http://192.168.1.100/plus background address
You can also point to other addresses in Apache.
This problem is generally not present on the server and is not modified.
