By the way, your script does not work in IE7 and below due to the weird standarts of IE: an array option cannot end with a comma.

options:{
    pixelBuffer: 400,
    pageVar: 'p',
    expireCacheMins: 20,
    pagesToPause: 5,
    loadingImage: '/images/loading.gif',
    moreText: 'Show More',
    disableCache: false,
    footerClass: undefined,
    contentClass: undefined,
    footerSpeed: 400,
},

The last comma (around footerSpeed, line 75) is extra. Removing it fixes the issue : )

@oguzhan.kahyaoglu Thank you, that was not intentional.
