Thread:Project:Support desk/Search Suggestions not working...

I'm using MediaWiki 1.16.2, and PHP Version 5.2.13. I am using the vector skin for my wiki.

In my LocalSettings.php, I have these settings:

$wgEnableAPI = true; $wgEnableMWSuggest = true; $wgOpenSearchTemplate = true; $wgUseAjax=true;

The wiki, if you need to see it, is here. The search suggestions just aren't working! Can anyone help?
