BP-Social 1.2.6 is no longer working with WordPress 3.2

After upgrade to WordPress 3.2, BP-Social 1.2.6 is no longer working correctly! One of the bug I notice is that at the front-page, when user clicked on newest, active, popular for members and group widgets, BP-social 1.2.6 failed to refresh the information or even display a correct information, as if nothing had changed but the underline bar of link had moved (i.e., from underlining newest to popular and so on)!
