opening a website with the selected language in a separate directory

[365Maksim]

Hello.
I ran into a problem, I didn't find an answer on the community.
whmcs with multilanguages works on one common directory: domain.net
I need the selected language to work with the language directory, for example: domain.net/de/
Please tell me how this can be done? Maybe there is a ready-made solution?

Have you tried .htaccess like this ?

RewriteEngine On
RewriteCond %{QUERY_STRING} ^lang=de$
RewriteRule ^$ /de/? [R=301,L]

Hello. Thank you, but unfortunately, that won't work. Additionally, I need support for multiple languages, not just one.

I'm trying to write the code in .htaccess:

RewriteRule ^([a-z]{2})/?$ index.php?language=$1 [L,QSA]

To display the link domain.com/de instead of the address domain.com/index.php?language=de. However, unfortunately, the site shows a 404 error page.

The same situation happens with Knowledgebase and Announcements. I assume this is due to internal link routing.

Please advise if it's possible and, if yes, how to make the necessary changes?
