It looks like your wiki is using w:c:dev:ShowHide for your collapsibles, which is an outdated script. While that script should definitely not be causing this problem, I would still highly recommend switching all your collapsibles to using  instead of.

See Help:Collapsing for more information. Since Wikia upgraded to MediaWiki version 1.19 in summer 2012, this style of collapsing is now built-in to the MediaWiki software, making the formerly-used ShowHide script obsolete.
