Thread:Project:Support desk/MediaWiki is ignoring LocalSettings.php

I have set up MediaWiki and it was working for a while. I enabled uploads and imported some stuff from an old wiki. MediaWiki is now giving me the following error:

(Can't contact the database server: Access denied for user 'wikiuser'@'localhost' (using password: NO) (localhost))

I have double checked, and the LocalSettings.php file contains the following settings:

$wgDBtype          = "mysql"; $wgDBserver        = 'localhost'; $wgDBname          = 'rachael_mw9'; $wgDBuser          = 'rachael_mw9'; $wgDBpassword      = 'password';

Anyone know what's going on?
