I can not change category order.
ERROR message "The lowest number you can assign is 1."
I did try change starting from 1

Been okay here on version 6 - do you have any category with a zero in it? Or perhaps using one number twice?

Shame you can't choose any number, and then it simply sorts on the numbers that it gives - as it can be a pain with 50+ categories getting them all in order, when the categories themselves are not sorted

I am use UBBT6.0

I am not have any category with a zero.
No using any number twice.

Do you have any categories with special characters in them? If so, these will break the HTML forms so the data doesn't come through correctly at this point.

Yes I have categories with special characters.
How I can change the order that the categories.

Right now the only way would be to edit the categories and remove the special characters, reorder and then change the categories back. Until I figure out how to get around the HTML form limitations special characters will always break this one.
