Solve the Magento background cannot login/Login No response method

Installed a few versions of Magento, installed after the landing in the background when all encountered a point of problem, the user name and password are entered correctly, is not landing backstage, after research found that landing is not the main background because of the Magento itself cache settings, the most template solution is as follows:

 magento can't login backstage can try the following methods to solve: Method One, with FF login backstage, in System-configuration-web-session Cookie management....timeout Instead: 86400 If the method is not one, use method two method two: still can't login please open file app/code/core/mage/core/model/session/abstract/varien.php  find code: Session _set_cookie_params (  $this->getcookie ()->getlifetime (),  $this->getcookie ()-& Gt;getpath (),  $this->getcookie ()->getdomain (),   $this->getcookie ()-&gt ; Issecure (),  $this->getcookie ()->gethttponly ());  replaced by: Session_set_cookie_params ($this- >getcookie ()->getlifetime (),  $this->getcookie ()->getpath (),//$this-> GetCookie ()->getdomain (),  //$this->getcookie ()->issecure (),  //$this-> GetCookie ()->gethttponly ());  These are found on the Internet, there are several versions of the Magento did this after the problem is resolved, but there are still some such settings after the login is not the background, So in Google continue to find the reason, finally in the Magento forum to see the following  magento1.4.1 after installation is not logged in the background, but the password and user name is correct, the solution: Open magento/app/code/core/ mage/core/model/session/abstract/varien.php find the following code, comment out $cookieparams[' domain ' = $cookie->getdomain (); it's OK.  if (Isset ($cookieParams [' domain]) {            $cookieParams [' domain '] = $cookie-& Gt;getdomain ();     }  results are as follows  if (Isset ($cookieParams [' domain ')]) {        & nbsp  //$cookieParams [' domain '] = $cookie->getdomain ();        }  But after doing this, there's still an error. , so I commented out all of the following  //if (Isset ($cookieParams [' domain ')]) {            //$ cookieparams[' domain '] = $cookie->getdomain ();    //     }
