Mybb Help

[sidorak95]

Ok, so I changed my forum to Mybb, changed the theme, changed the logo, and everything seems to be running smoothly. I delete the pre-made forums to make my own and now it's saying that I must choose a parent forum. I have no other forum so the only choice is None. However, if I choose None, it says, "You must select a parent forum." Is there an easy fix, or do I have to reinstall everything?

Thanks.
