Language switching does not work when browser language is configuired in drupal 8.3.7

Question

Language switching fails after enabling browser on Detection and selection

/admin/config/regional/language/detection

Exisiting :

On switching language from the browser the url changes but the content remains the same

E.g, Default language browser is Germen.

mywebsite.com mywebsite.com/about etc shows German content.

While swiched to English url changes to mywebsite.com/en mywebsite.com/en/about etc

It shows Germen content instead of English.

Expected

On browser configured with Germen as default language, the site url should be mywebsite.com/de.

When I swich to the English website, it should show English content

Please find the configuration.

Answer 1

It is very obvious why this is happening. Language selection process the language detection systems from top to bottom. (Top has highest priority.) Your configuration means that the browser will always be selected first and that url and user settings are ignored.

If you move browser below user (drag with the arrows icon), the processing order will be:

• url
• user (if url resolved no language)
• browser (if user had no language configured)

Answer 2

I have fixed the issue with htaccess.Please refer this code,it may be helpful for similar issues.

  ## On frontpage redirect to /de if the browser language start with de
  RewriteCond %{HTTP:Accept-Language} ^de.*$ [NC]
  RewriteCond %{REQUEST_URI} ^/$ [NC]
  RewriteCond %{QUERY_STRING} !(^q\=) [NC]
  RewriteRule ^(.*)$ /de [L,R=302]

  ## On frontpage redirect to /en if the browser language start with en
  RewriteCond %{HTTP:Accept-Language} ^en [NC]
  RewriteCond %{REQUEST_URI} ^/$ [NC]
  RewriteCond %{QUERY_STRING} !(^q\=) [NC]
  RewriteRule ^(.*)$ /en [L,R=302]

  ## To make all other requests (that is, URLs not starting with /en/ or /de/) redirect to a default language (say en)
  RewriteCond %{HTTP:Accept-Language} () [NC]
  RewriteCond %{REQUEST_URI} ^/$ [NC]
  RewriteCond %{QUERY_STRING} !(^q\=) [NC]
  RewriteRule ^(.*)$ /en [L,R=302]
