Thread:Project:Support desk/Wiki syntax error, unexpected/reply (2)

I'm pretty sure you're on a free hosting service, which automatically adds scripts to the page to display ads, and it added that script when MediaWiki prompted you to download the generated LocalSettings.php file. If you're installing MediaWiki in such host, it will not work, because it will try to append that script in load.php URLs and will break scripts and styles of MediaWiki.
