WP Residence Theme - Mobile/Tablet Menu Language Switcher Redirects to Wrong Page

Overview of the issue

When using the WP Residence theme with WPML, the language switcher located in the Mobile/Tablet burger menu may redirect to unrelated URLs instead of the translated version of the current page.

Workaround

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

• Open the …wp-content/plugins/wpresidence-core/api/inc/menu_functions/menu_functions.php file.
• Look for line 156.
• Replace:

  $mobile_menu = get_transient($transient_name);
          

• With:

  $use_cache = ! has_filter( 'wpml_active_languages' );
  $mobile_menu = $use_cache ? get_transient( $transient_name ) : false;
          

• Look for line 198.
• Replace:

  set_transient($transient_name, $mobile_menu, 60 * 60 * 24);
          

• With:

  if ( $use_cache ) {
    set_transient($transient_name, $mobile_menu, 60 * 60 * 24);
  }
