[SOLVED] .htaccess News Manager + I18N setup

[TeeJay]

The I18N plugin uses two approaches to determine the language. Either the language is included in the URL (lang=xx) or the language is determined from the user's browser's language settings.

Thus not specifying the language in the URL for your default language will have it fall back to using the browser settings, which might have "cs" first for one user and "en" first for another user.

The default language in the settings is used only, if the browser settings are used, but none of the languages in the browser match the site's languages.

I see. That's how it works.

Why it worked for Carlos is that he has a Spanish browser and the default language he use is also Spanish.

But I have an English browser and use Czech as a default language, so it switches my language only.

This is very good to know.
Thanks for the explanation Mvlcek.
