Sanguine Oh, I'm sorry!
With domain problems, some time ago I migrated all the content of the extension to: tiu-ram0n/brazilian-portuguese on packagist.

I don't think I can use it: tiu-ram0n/flaneo-ext-brazilian-portuguese for this reason.
Try to uninstall the version tiu-ram0n/flaneo-ext-brazilian-portuguese and install this version: tiu-ram0n/brazilian-portuguese

Install command line:

composer require tiu-ram0n/brazilian-portuguese

I'm really sorry for having to put you through this, I'm sorry!

    ram0ng1 Yes, I tried that already, the working 1.1.9 copy is from the old location (from my cache). Everything 1.1.12 and up from the new location does NOT work.

      Sanguine I finished testing locally on a clean installation and it works fine for me.

      I really don't understand what's going on. I'll try something more in-depth and give you an answer.

      Receiving this error in the console while the extension is enabled. The page content then doesn't load (just Flarum's header):

        I will do a test locally and I will give you a solution.

        SKevo Hey,

        I had no major problems with installing the language pack. Could you try to remove the package and try to install again ?!

        or try

        composer update tiu-ram0n/brazilian-portuguese
        php flarum cache:clear

          ram0ng1 I'm sorry to say, but even after reinstallation, the issue still persists... Same as before and I have no idea what could be causing it. Using beta.15

            Thank you for letting me know!
