yup, i tried to add and modifying existing category but it failed. i also got trouble with my redis, i think i will use mongo as my DB than redis, i prefer use redis only for cache ing or as message broker.

is there any how to install with mongoDB?
i try to set user and password in mongo and run node app.js --setup and choose mongo as my db but also failed. may be nodebb need specific database name?

thanks for your response

is there a limit for create category? i tried to add more but it seems cannot create more category.
