Hello,
It seems that error messages such as “Login already exists.” is not part of the Translation.
How do I go about translating all error messages? Modify files? Create a new set of files for our translation?
Hello
you can specify your version of Dolibarr and the language selected for your display
in fact in “htdocs/langs” directory you can find every set of files for translation in Home - Setup - Translation menu
Good continuaton
Thank you for the reply.
Great to know the language files are in htdocs/langs.
Upon grep’ing the whole htdocs/langs, for example, error message “Login already exists” is not in any of the languages.
I wonder where the system messages are stored.
Can you share more?
Hey 
Search the key “ErrorLoginAlreadyExists”
Good continuation
