NexDog, I have no idea, it works fine on my 2.2.6 board, are you running a diffrent verson?
trilOByte - I will admit that it can take up quite a bit of database space, but if you think about it most of the chapters are not going to be huge or anything, and if you are running a forum anyway then it's lickly that you are going to have enough space anyway.
But if you are worried about it, just edit the $max_chapters variable in the vbstory.php file to a lower number.
I would love to offer some type of soloution, i.e. reducing the space it takes, but I don't think there is one, it's just a case that if the story is popular enough to fill up your database, then you must have a popular site in which advertising, etc... money coming in should be fantastic
