Today's BuddyPress TOS update not working

i see that this plugin was updated today. i'm talking about the one at https://premium.wpmudev.org/project/buddypress-terms-of-service

latest wp multisite, latest bp. when i try to save the tos in super admin, i get a page not found error after clicking "save changes".

funny thing is that i had an earlier version working just fine a couple of days ago...
