Write your message below:

Receiving the can't execute SQL error when attempting to add a new knowledge base category. It doesn't matter whether it is a private or public category.

Creating a new article works fine.

I can manually create a category directly in the database and then edit the category name from the admin area on the help desk application.

Turn "Debug mode" to ON in Settings > Help desk tab then try again and see what error message do you get?

Your database isn't properly setup.

Did you run the "update" script when updating your help desk to version 2.5.x as explained in docs?
