Thread:Project:Support desk/Collapsible tables not collapsing anymore in FF9, Opera, Safari

Website: http://www.princevault.com/index.php/Main_Page MediaWiki 	1.14.0 PHP 	5.2.13 (apache2handler) MySQL 	5.0.77

Example of page with a collapsible section: 

The section underneath "Release" should be collapsed.

I noticed very recently that the collapsible tables in my wiki don't collapse anymore, except in Chrome (on Mac but not on PC (??)). Please note that the collapsible tables have worked correctly on the wiki since day one (February 2009). Today I read every documentation here, especially Manual:Collapsible_elements. I did create a Common.js and a Common.css, but it's not solving the problem.

I should upgrade my wiki to 1.18 but I have met too many problems with the process lately, to proceed.

Thanks In advance for your help.
