[WP User Manager] Language Switcher Redirects to the Main Profile Page Instead of the Specific User Profile

Overview of the issue

When using WP User Manager plugin, switching languages on a public user profile page (e.g. /profile/username) redirects to the main profile page (e.g. /fr/profil/) instead of the specific translated profile (e.g. /fr/profil/username).

Workaround

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

• Edit your theme’s functions.php file and add the following function:

  // WPML Workaround for compsupp-8195
  // Preserve WPUM profile sub-path when switching languages with WPML.
  add_filter( 'icl_ls_languages', function( $languages ) {
      // Only run if WPUM
      if ( ! function_exists( 'wpum_get_core_page_id' ) ) {
          return $languages;
      }
   
      // Get profile info from query vars
      $queried_profile = get_query_var( 'profile', false );
      if ( ! $queried_profile ) {
          return $languages;
      }
   
      // Build the trailing path from query vars
      $trailing = '/' . rawurlencode( $queried_profile );
   
      // Add tab and pagination if present
      $tab = get_query_var( 'tab' );
      if ( $tab ) {
          $trailing .= '/' . rawurlencode( $tab );
      }
       
      $paged = get_query_var( 'paged' );
      if ( $paged ) {
          $trailing .= '/page/' . rawurlencode( $paged );
      }
   
      // Append to each language URL
      foreach ( $languages as $key => $lang ) {
          if ( empty( $lang['url'] ) ) {
              continue;
          }
          $languages[$key]['url'] = rtrim( $lang['url'], '/' ) . $trailing;
      }
   
      return $languages;
  } );
