Endless loop Setting up database while install Drupal

Drupal is an open source CMS. If you setup it for the first time you will get a lot problems. One common problem is this: During the installation it will ask you to setup the database. But even you put the right database name, username and password in, the installation wizard will not go the next step; instead it will stay at the same page asking for the same information again and again. This problem may be caused by a missing file. That file is “default.setting.php” under “site\setting”. When you install Drupal, you may accidently renamed the file to “setting.php”. If you did, rename it back and create a empty “setting.php” file under the same folder.
