Buddypress registration not working

my buddypress registration suddenly vanished out of thin air, (was messing with the w3 cache, but i doubt that did it. as i reset everything) i tried to create a new registration page, and linked it, but still no luck.
Need help bringing it back to life.

let me know if it works for you. http://www.miora.org/register/

i deactivated buddypress, the registration for wordpress works.
