[Resolved] The language switcher on the mobile menu is only showing a piece of coding

Problem:
If you're experiencing issues with the language switcher on your mobile menu displaying coding instead of language flags and names, it's likely due to the theme bypassing

wp_nav_menu()

and its walkers, using

wp_get_nav_menu_items()

to grab raw items and rebuild its own HTML, which breaks the language switcher.
Solution:
We recommend you try the following steps to resolve this issue:
1. Ensure you have a backup of your site.
2. Open the

...partials/headers/parts/mobile_menu.php

file.
3. Locate around line 17, right below the line:

foreach ( (array) $menu_items as $key => $menu_item ) {

4. Add the following code:

// Detect WPML LS with class 'wpml-ls-item'<br />$classes = is_array( $menu_item->classes ) ? $menu_item->classes : array();<br />if ( in_array( 'wpml-ls-item', $classes, true ) ) {<br />$menu_list .= '<div class="stm_lms_categories_dropdown__parent">';<br />$menu_list .= do_shortcode( '[wpml_language_switcher]' );<br />$menu_list .= '</div>' + "\n";<br />continue;<br />}

Alternatively, you can use a custom language switcher and add it manually to the theme templates. For more details, visit Adding Language Switchers using PHP and Shortcodes.
