update Ecommerce webserver with a new mySQL database password - akoston/McK-CCDC GitHub Wiki

You will need to change the password in the following files:

includes/configure.php

admin/includes/conifgure.php

Look for the line

define('DB_SERVER_PASSWORD', '');

here the line will look like ('DB_SERVER_PASSWORD', 'mypass')

towards the bottom.

and if the configure.php has 444 permissions temporary change to 666 to allow you to overwrite then change back to 444 as recommended
