Thread:Extension talk:LiquidThreads/I'm newbie : I completed install liquid threads but..

I completed install liquid threads but I can't 'start new discussion' link. Exactly, when I click link, a circle-shaped wait indicator appeared in page, but the page ever pass to next phase.

I installed setted LocalSetting.php like this:

require_once("$IP/extensions/LiquidThreads/LiquidThreads.php");

and I runned update.php.

I'm using on Apache server on Windows 7 Professional with MySQL.

ps. Is it possible relationship with $wgHook setting? I'm newbie on mediawiki and server admin so I did nothing set about any hooks.

HELP ME PLEASE!!
