The display of that empty option is suppressed in 1.0 when it isn’t available.

It’s only ever visible to admins anyway, so it wasn’t a huge deal.

Turns out there is an error in 0.9 that stops the “throttle_time” option from being set.

If you run this raw SQL on your database it should set the option to 30 seconds which will force a checkbox to show up in that form.

INSERT INTO bb_topicmeta VALUES (NULL, '0', 'throttle_time', '30');
