When we Install Joomla on our machine and we Log into Joomla administrator, after that when we enter the username and password, it will not taken us to the admin page, instead of landing to the admin page we get redirected to the same login page without displaying any error message even we enter the correct username and password.

This is generally caused by incorrect configuration settings. The configuration settings are present in a configuration.php file present in our Joomla Installation folder.

Here is the solution, the change that we do is, set the cookie domain and cookie path to be empty.

open the configuration.php file in Joomla folder and make the changes:

//public $cookie_domain = localhost/joomla';
public $cookie_domain = ;
//public $cookie_path = /';
public $cookie_path = ;

Now, we will be able to login to the Joomla admin.
