Yes, in project setting.

AFAIK, a category has just a name?

--------------------------------------------------------------------------------
yes, I can add them from project setting, but why would it be different for the first category ?
Also, about category name, please see :

!cat1.png!
!cat2.png!

thanks

It's a simple way to hide the Category field (or Version field) to people who don't need it.

Got the same issue. What's your Redmine version?
--------------------------------------------------------------------------------
I'm using redmine devel (r8091). The problem appeared 2 weeks ago approximately.
thanks

Guess it's due to r7881, guess that the error is in @IssueCategoriesController#create@.

Version field works fine.

Fixed in r8096 and merged in 1.3-stable.
