BuddyPress.org

I installed the theme to see what I could see.

The problem is caused by the following lines in fusion/js/fusion.js:

jQuery.fn.fadeOut = function(speed, callback) {

return this.animate({opacity: 'hide'}, speed, function() {

if (jQuery.browser.msie) this.style.removeAttribute('filter');

if (jQuery.isFunction(callback)) callback();

});

};

(lines 56-61 in the version I downloaded). I don’t know exactly what the problem is, but if you delete those lines then the activity filter works again, at least on my local version.
