I've been working on a Drupal site and pretty much know how to install Drupal on the localhost. But when I downloaded the existing source code from the main site to my system ( using FTP ), I am unable to install the site inspite of changing the database url in the settings.php file.
Also, when I run localhost/site/install, I am able to complete the installation but when I view the existing site ( localhost/site ) I am not able to see any content.
I am using Ubuntu 12.04 and Druapl 6.x.
Any kind of help would be greatly appreciated.
Update : Solved the above issue. Thanks to roberthernandez. But the site which I downloaded is not installed as it should be. All the modules and themes in sites/all are available but, nothing is configured as it should be.
Update 2 : I asked a new question on the above issue. Please follow the link
