Try to disable and re-enable the language pack and run php flarum cache:clear

    Kylo Already tried that various times with each language pack (english and french) without success 🙁

      Do you see any files ending in .js or a rev-manifest.json in your public/assets directory?

        Sounds like your permissions are incorrect. For the translations to be shown a js file is generated for the locale, eg forum-en-<hash>.js; if Flarum cannot write to the assets directory these files won't show.

          luceos Strange as I didn't change anything on my side.
          My public/assets rights are set to 755. what should it be?

              Th0mC chmod isn't that important on modern webservers, what matters is who the web user is and whether that user can write into the directory. Usually the web user is www-data and as such chowning the assets directory to that user (and all underlying files) should help:

              sudo chown -R www-data: assets

                  luceos All directories and sub-directories are own by the webserver user cdlpweb in my case 🙁

                    give a try to 777 rights on public/assets. Desactivating/reactivating language pack without success

                      Th0mC can you show the output of

                      ls -la .
ls -la public/assets

                          luceos Of course 🙂

                              Th0mC you have both an assets and public/assets directory? Which of these is actually in use?

                                  luceos Ha should be only one :/
                                  Seems to be assets as there are many files here, including .js file I think you were mentioning

                                      Th0mC yes but which directory is being used 😕 .. This could be the cause of your issues, Flarum compiling the files to the assets directory, but trying to read them from public/assets because you configured your webserver to load public.

                                          Seems to be the issue because I can't see anymore uploaded files in some discussions 🙁
                                          But I didn't change anything and it was working before the upgrade to beta12.
                                          How can I reset that?

                                          Edit: Uploaded files issue is not a proof, as I'm not able to reactivate fof/upload extension after upgrade

                                          luceos
                                          Didn't find where this parameter could have changed
                                          + I tried to copy both admin-fr-85026ab9.js and admin-fr-85026ab9.js.map in /public/assets with French pack activated to test but it didn't change anything 🙁

                                            luceos Tried to copy all assets directory to public/assets too with no effect.
                                            I'm lost 🙁
                                            Any kind of help more than welcome 😉
                                            Thanks

                                              Little step.
                                              Finally I activated both English and French pack.
                                              Switched on the homepage from French to English
                                              And Tadam! It works in english but still not working in French 🙁

                                              Th0mC changed the title to beta 12 - incompatibility fof/subscribed with language pack .
