Fresh xampp install, upon entering localhost/mapthatiputunderhtdocs (witch contains an existing wordpress website) there is a 'Error establishing a database connection'. When i enter http://localhost/xampp/index.php there is no problem. when restarting apache this is in the error log :

This is a wordpress configuration issue.

You provided the wrong credentials to the wordpress config file, but as long as you dont show us, what you applied, we cannot help you.
