I solved, first active mention's extension, after going to phpmyadmin, in the settings table ----> extensions_enable. I cadded the field to, "flarum-mentions" and saved.
After doing everything clean the flarum and browser cache.

    Kyrne the extension has failed. I wrote to you on discord with a pm.

            There's a bug in firefox that means you cannot expand replies (for me, and my users anyway, who have all reported it)

            addUserInfo.js:103 Uncaught TypeError: n.ranks(...).reverse is not a function
            at e.<anonymous> (addUserInfo.js:103)
            at e.t.<computed> [as view] (extend.js:27)
            at e.render (Component.js:100)
            at e.n.headerItems (CommentPost.js:134)
            at e.t.<computed> (extend.js:25)
            at e.t.<computed> (extend.js:25)

            at e.n.content (CommentPost.js:50)
            at e.t.<computed> [as content] (extend.js:25)

            Works fine in Chrome etc, but not in firefox - even with cache cleared, and incognito session.

            EDIT:

            Now I've managed to reproduce it where it works in Firefox, but not Chrome - same error message though ?

                  Kyrne Thanks for this. Is there a setting that can be enabled for all replies to be expanded automatically ?

                      2 months later

                      after I activate kyrne extension my flarum not working . how can I remove that . composer remove not worked?

                        fatihaysel

                        composer remove kyrne/evergreen
php flarum cache:clear

                            luceos Thanks for the reply, i noticed i cant edit tags from the admin end. when i click the pencil icon it doesnt click

                              luceos ıts not solve my situation. if I go inside administration flarum freeze.

                                  fatihaysel most likely another (installed and enabled) extension is causing these troubles.
