I too am experiencing this problem, and while I hope it is fixed soon (is the update automatic?) it certainly won't drive me away from this very decent software =)
@Above post, I swapped to Nabble today from Weebly's new Tal.ki forums -- that service is terrible because it forces users to sign up for a Weebly account before they can even post on your forum (and without the upgrade service, it is very, very restricted), and doesn't even have basic features like post counts. I cancelled my subscription today, only a couple of days in.
