Plugin WP-Polls is throwing a wierd error please help

Hi,

I’m using WP-Polls 2.3.1 (for wp v2.6.x) and I am experiencing a wierd error when either the vote is made, or you click the view results button. Basically nothing is happening when those are clicked.

Firebug is saying this error which links to wp-includes/js/tw-sack.js…
uncaught exception: [Exception... "Cannot convert WrappedNative to function" nsresult: "0x8057000d (NS_ERROR_XPC_CANT_CONVERT_WN_TO_FUN)" location: "JS frame :: https://theinnercircle.org.za/wp-includes/js/tw-sack.js?ver=1.6.1 :: anonymous :: line 20" data: no]

You can replicate the error by navigating to https://theinnercircle.org.za/index.php?page_id=46 and clicking on the poll on the bottom left of the sidebar/nav.

I’d appreciate your help, I’ve had a freelancer hack this together and I’ve been spending a month fixing it!
