I'm glad you published this one day prior to me searching for a Portuguese translation.

I won't promise anything but I will try to modify your extension to PT-PT and republish it.

Edit:

I was trying to install this extension but get this error.

    VIRUXE flarum- is stripped when moving the extension into the extensions directory. This might cause the mentioned issue.

        Thank you guys, i will find a fix for this problem.

        The package is now updated and i made some instructions, please see the first post.

        Now, can any dev help me?
        I'm testing the translation in my local instance and there's a bug that i really can't fix. (tried, but nothing)
        For example, when i'm creating a post, instead of the "submit" word in the button, i'm seeing:
        "core.forum.composer_edit.submit_button"
        It can be a problem with my computer too.

          Azhir_Khallav I will test this as soon as I get off work. And also try to translate the rest of the french. I don't know much french but I'm sure I'll figure it out from the constants.

            Thanks @BlackSheep and @VIRUXE.

            @VIRUXE, if you can, i appreciate your help.
            About the french language problem, i'm reverting the files in french to english, to make the job more easy.

              VIRUXE It was a bug with the config.js file, but now it's fixed.
              Edit: Now you are a contributor of the project.

                  Yep, just a single file bug.

                  I updated the repo with the fixed file, you can download and test it, the bug was with a unnecessary "{" (thanks for firefox console).

                  I'm planning to keep translating Flarum, but now i don't have much time, so feel free to help the project if you can 🙂

                      VIRUXE No problem, being portuguese is great, but try to not use too much regional words.
