How to correctly set language of the site?

I don't want to use multilingual features, i just want to set default language to kazakh for example, instead of english.

In system.yaml:

languages:
  supported:
    - kk
  include_default_lang: false
  translations: true
  translations_fallback: true
  session_store_active: false
  http_accept_language: false
  override_locale: false

I've set kk as ONLY supported language. But when i create a new page from admin panel, i get this:

It's creating a new page with postfix page.kk.md - is this a bug? If i have a single language, why it's postfixing my pages...

Again, I have limited translation or multi-language experience ... I wonder of you simply rename this file and remove the language code (to page.md), if it will route and load correctly.

Setting some things up through Admin, in my experience, it seems to sometimes use the safest option to save files and details, and this can include redundant details. Another example is changing system configuration - Admin will create an override for your environment rather than a global change.

I could be completely wrong! 🤔

If i rename it back to page.md - it works again, but all newly created pages are coming with postfix :S

That's what I meant. It's just the way Admin does it. Rename them all or create them using a text editor. I work outside Admin mostly because of this kind of behaviour.

The problem is not only i will be using this website, that's why admin plugin is needed. I just wonder, no one faced this issue before? Grav existing is ~2 years already, and nobody faced that?

Are you sure nobody has faced it? Search for issues on Github and add a new one. Explain why it is a problem. Some in the community will say this is not a big problem, like they did when I pointed out duplications in the config files when editing in Admin. I never logged an issue but I should 😣

Because this is related to filenames that site users don't see (URLs would be different), I personally don't think it's a massive problem but I am interested to hear your arguments.

Just checked issues in admin plugin on github, none were found. It's just strange, i can't find in source code of admin plugin where's that functionality that adds postfixes.

Well, maybe it's expected behavior? Because when i've created the pages while i had supported languages set to none, it was just page.md, now i've set kk and it adds kk too all corresponding .md files.

Could you upload your system.yaml file ? (user/config/system.yaml).
I do have a website in french only without the language in the folders.

My system.yaml looks like that :

languages:
  include_default_lang: false
  translations: true
  translations_fallback: true
  session_store_active: false
  http_accept_language: false
  override_locale: false
  supported:
    - fr  

user/config/system.yaml:

languages:
  supported:
    - kk
  include_default_lang: false
  translations: true
  translations_fallback: true
  session_store_active: false
  http_accept_language: false
  override_locale: false

Are you adding pages through admin panel?

Well,
I've just made a test.

I created a page through the admin panel, it has the language in the file name. whatever.fr.md

But when I had created the website, some pages were created through the admin, some not. Some pages do have the language in the file name, some not.

Anyway, they are all working the same.

So i guess it's expected behavior for pages created via admin panel

Have you read documentation?
https://learn.getgrav.org/content/multi-language
You have enabled multi-language support and now your new pages has language id in their file names. Everything works as expected.

I've read it many times, please, read yourself it closely: Single language different than English

It doesn't say that i've enabled multilingual functionality, just changed default language. That's why i wondered - why postfix were added.

I'm understand you. But you enable multi-language functionality with single language. 🙂 I think it can be better set language in theme settings.

Theme language not doing anything at all.

By default no. If you build your own theme or change existed, you can use own language logic in twig templates.
