Ok I figured out the problem.

I saw you explaining that the “submit” button must be pressed twice to visualize the autorized users on the restricted forum.

The problem is that the second time you press submit, a blank text field is sent via bb_update_option, thus rendering the forum unrestricted.

If you press submit just once everything runs smoothly.

And BTW, thank you very much for this excellent plugin, I needed a staff only forum *badly*
