While installing Drupal sometimes you might get stuck on the database configuration page. After entering the data and
submitting, the page just reloads and nothing happens. Follow the below steps for the solution.
1. I know you have already done this step, but just to mention, please go through the database details once again and
confirm they are all OK. The username, password, database name, host everything.
2. Open sites\default\settings.php
Search for $db_url =
Enter the database details manually. The format is described below
mysql://username:password@localhost/databasename
Replace username, password, localhost and databasename with database user name, database password, database host
and database name respectively
If no database password is set (mostly when using local installation) the format would be
mysql://username@localhost/databasename
