Error establishing a database connection in WordPress on MAMP

I’m setting up WordPress on my local machine using MAMP and encountering the “Error establishing a database connection” message. Here are the steps I’ve taken:

1. Downloaded WordPress and extracted it to my MAMP htdocs folder.
2. Created a new database named wp in phpMyAdmin.
3. Used the following configuration details during the WordPress setup:
   • Database Name: wp
   • Username: root
   • Password: (left blank for MAMP)
   • Database Host: localhost
   • Table Prefix: wp_

I duplicated wp-config-sample.php to wp-config.php and updated the database connection details, but I still receive the same error. I’ve also tried using the original values from wp-config-sample.php.

What am I doing wrong? Any help would be greatly appreciated!
