      Trailou And I tried without ssh :

      Suddenly that part makes a lot more sense 😉

      You mean https, not ssh 😉

      Trailou what does your config.php file say?
      eg

        'url' => 'https://www.domain.tld',

      I tried

      'url' => 'http://' . $_SERVER['HTTP_HOST'],

      according to @santiagobiali advice but no luck.

      Here is my config.php :

      <?php return array (
      'debug' => true,
      'database' =>
      array (
      'driver' => 'mysql',
      'host' => 'db6116555.db.1and1.com',
      'database' => 'database',
      'username' => 'username',
      'password' => 'password',
      'charset' => 'utf8mb4',
      'collation' => 'utf8mb4_unicode_ci',
      'prefix' => '',
      'strict' => false,
      ),
      'url' => 'https://www.tracedetrail.com/forum/flarum',
      'paths' =>
      array (
      'api' => 'api',
      'admin' => 'admin',
      ),
      );

        @Kulga No answer yet from my hoster...

        I also tried to install flarum in the root of my webspace in a forum directory. I create a subdomain forum.tracedetrail.com for that.
        After installing composer project, I get this error :

        Parse error: syntax error, unexpected 'finally' (T_STRING), expecting catch (T_CATCH) in /homepages/6/d296193771/htdocs/forum/flarum/vendor/flarum/core/src/Foundation/Application.php on line 119

        when I go to this web page http://forum.tracedetrail.com/forum/flarum/ to finish installation.

        Thank you again for your help !

          @luceos You're right, by default, my hoster put the v 5.4 for this subdomain ! I'ts corrected...

            The installation is ok, but same issue when I start a discussion :-(

            POST discussions 401 Unauthorized forum.tracedetrail.com

              Kulga And for this installation, I didn't change default htaccess in Flarum directory.

              Trailou
              Is it possible to make it accessible at forum.tracedetrail.com rather then forum.tracedetrail.com/forum/flarum? (or even forum2.tracedetrail.com)
              Making sure your config.php reflects this.
              Being in a subfolder has caused issues in the past - trying to isolate the problem.

                Kulga It's done : the forum is accessible at http://forum.tracedetrail.com/
                I changed my .htaccess (RewriteBase / added), but I get always the same issue :

                POST discussions 401 Unauthorized forum.tracedetrail.com
