Thread:Project:Support desk/Extension:ToggleDisplay doesn't work for me.

Hi,

I am using mediawiki locally in my desktop and recently I've installed ToggleDisplay extension by following instructions in Extension:ToggleDisplay, but when I use it as

This will be shown.

any texts, even toggle links are not shown. The block of toggledisplay disappeared from the page.

I've spent two days to solve this problem, but no luck so far.

Does anyone have any idea?

I am using:

MediaWiki : 1.16.0

PHP : 5.3.3

mysql : 5.1.48

Bests,
