Overview of the issue

In BuddyBoss, when discussions are translated, the translated versions may not have the correct forum assignment and might not display within the forum loop. This issue can lead to translated discussions not appearing under the corresponding translated forums on the frontend.


Please, make sure of having a full backup of your site before proceeding.

  • Go to WPML > Settings > Custom XML Configuration page.
  • Add the following XML:
        <custom-field action="copy-once">_bbp_forum_id</custom-field>
        <custom-field action="copy-once">_bbp_last_active_time</custom-field>
        <custom-field action="copy-once">_bbp_activity_id</custom-field>
        <custom-field action="copy-once">_bbp_author_ip</custom-field>
        <custom-field action="copy-once">	_bbp_reply_count</custom-field>
        <custom-field action="copy-once">_bbp_reply_count_hidden</custom-field>
        <custom-field action="copy-once">_bbp_topic_id</custom-field>
        <custom-field action="copy-once">_bbp_voice_count</custom-field>
  • Open your theme’s functions.php file.
  • Add the following PHP code:
    // WPMl Workaround for compsupp-7242
    function wpml_compsupp7242_filter_bbp_get_topic_forum_id($forum_id, $topic_id) {
        if ( class_exists('Sitepress') ) {
            $forum_id = apply_filters('wpml_object_id', $forum_id, get_post_type($forum_id), TRUE);
        return $forum_id;
    add_filter('bbp_get_topic_forum_id', 'wpml_compsupp7242_filter_bbp_get_topic_forum_id', 10, 2);
    // I'm not sure if this other filter is really needed, but I'm also adding here for reference
    function wpml_compsupp7242_filter_bbp_get_forum_id($bbp_forum_id, $forum_id) {
        if ( class_exists('Sitepress') ) {
            $bbp_forum_id = apply_filters('wpml_object_id', $bbp_forum_id, get_post_type($bbp_forum_id), TRUE);
        return $bbp_forum_id;
    add_filter('bbp_get_forum_id', 'wpml_compsupp7242_filter_bbp_get_forum_id', 10, 2);
