Hi Luis,
Thanks for your suggestion. I'm pleased to advise that ticket statuses can be translated via language files: https://developers.whmcs.com/languages/

For example to translate the Open ticket status:

[co]
  • $_LANG['supportticketsstatusopen'] = "Your Translation";
    • [/co]

    To translate a custom ticket status:

    [co]
  • $_LANG['supportticketsstatuscustom'] = "Your Translation";
    • [/co]

    Where "custom" is the name of your custom ticket status.
