Language of the Web page couldn’t change to be which I wanted

I’m interested in language but it’s really tired when something wanna realize right now.
I’m so sorry that I couldn’t find the step to change my personal language on “automators”, is anyone give me a hand?
I’m so apologize for having so many stupid questions.

There is an option for the Discourse software, but I don’t see an update in the user interfaceand it is supposed to be set automatically at sign-up from what I can tell (based on locale); unless the system is configured to only offer English?
