At this page https://area51.phpbb.com/docs/dev/32x/language/validation.html the link to the CDB is not working, it gives the user a 404 error: https://www.phpbb.com/go/customise/language-packs

Should be something like:

• https://www.phpbb.com/languages/
• https://www.phpbb.com/community/app.php/db/language_packs-25
