You've done something wrong for sure. This is a syntax error and this is a result of incomplete or inaccurate changes.

In any case you if you don't want to show sub-forum with parent forums you can disable the  "Threaded Layout - Display Sub Forums with Parent Forums" option in Dashboard  >Forums > Settings > Forums Tab:

PHP Parse error: syntax error, unexpected '}', expecting end of file in /var/www/html/omissis.net/wp-content/themes/rehub-blankchild/wpforo/functions.php on line 22,

I need to show subforums at the bottom and topics above or the solution i see here i like it too

Thank you

The changes worked originally but it is not update proof, I lost changes on last update to plugin

The /wpforo/ folder should be in the active child theme folder not next to.

My only concern is whether I created the update safe copy correctly. I copied the forom.php part of the plugin and I have used File Manager in my hosting to create a WP Foro folder and save it under wp-content > themes. 

It is next to the folder I used for my child theme.

Is there a tutorial for this to check if I have saved correctly?

What do you mean saying "on entire community? It should not be displayed on the home page.

The sub forums should only be displayed in the parent forum page. For example, when you're on the home page, and you click on a parent forum title and go that forum page, instead of the sub-forum list you should see only the drop-down as I showed it on the screenshot.

Please let me know whet template file have you used to insert the function? You should use the forum.php file directly in the /wpforo/wpf-themes/classic/ directory.

Can I see a screenshot of your change and copied file?

It's actually not a bad layout for the time being, but I would be curious to see the drop-down. I have cleared cache through WP Rocket

1) Show main forum content before sub-forums.

2) Enable a sub-forum drop down menu.

3) Enable sub-forum pagination.

Thank you for the suggestions @jwhit16,

We've added this in our to-do list. Currently, let's try to create the #2 using a simple custom code. But it'll look like this and it'll jump to selected sub-forum once you choose it:

https://wpforo.com/wp-content/uploads/2020/04/2020-04-21_0034.png

Please follow the instruction below:

1. Put this function in your active WordPress theme functions.php file:

function wpforo_custom_subforum_dropdown(){
    if( function_exists('WPF') ){
       if ( WPF()->current_object == 'topic' && wpfval(WPF()->current_object, 'forum', 'url')
        ) {
          $args = array( "parentid" => WPF()->current_object, "type" => 'forum' );
          if( $forums = WPF()->forum->get_forums( $args ) ){
             ?>
                <div class="wpf-sub-wrap">
                    <select class="wpf-sub-forums" onchange="window.location = this.options.value">
                        <option value="<?php echo esc_url_raw(WPF()->current_object) ?>"><?php wpforo_phrase('Sub-Forums'); ?></option>
                   <?php
                   foreach ( $forums as $forum ){
                      if( WPF()->perm->forum_can( 'vf', $forum ) ) {
                         $forum_url = wpforo_forum( $forum, 'url' );
                         echo '<option value="' . esc_url_raw( $forum_url ) . '">' . $forum . '</option>';
                      }
                   }
                   ?>
                    </select>
                </div>
             <?php
          }
       }
    }
}

2. Put this CSS code in Dashboard > Forums > Settings > Styles Tab > Custom CSS Code textarea. Save it, delete all caches and reset optimizer / minifier plugins cache if you have any:

#wpforo #wpforo-wrap.wpft-topic .cat-stat-questions,
#wpforo #wpforo-wrap.wpft-topic .cat-stat-answers,
#wpforo #wpforo-wrap.wpft-topic .cat-stat-posts{display:none;}
#wpforo #wpforo-wrap.wpft-topic .wpf-sub-wrap{width: 100%; background: #f5f5f5; padding: 10px; }
#wpforo #wpforo-wrap.wpft-topic .wpf-sub-forums{width: 90%; margin:0 auto 0px auto!important; display:block;}
#wpforo #wpforo-wrap.wpft-topic .forum-wrap {border-top: #cccccc 1px solid;display: none;}

3. Create an update-safe copy of wpForo Q&A layout forums.php file,

3.1 Create /wpforo/ folder in WordPress active theme directory,

3.2 Copy /wp-content/plugins/wpforo/wpf-themes/classic/forum.php file to the /wpforo/ folder,

3.3 Edit the copied /wpforo/forum.php file, find this part of code:

else : ?>
   <p class="wpf-p-error">
      <?php wpforo_phrase('No forums were found here.') ?>
   </p>
<?php endif;

3.4. Add the new custom wpforo_custom_subforum_dropdown() function before that code. It should look like this:

wpforo_custom_subforum_dropdown();
else : ?>
   <p class="wpf-p-error">
      <?php wpforo_phrase('No forums were found here.') ?>
   </p>
<?php endif;
