[Resolved] Logo link in header always links to German version

Sorry, but could you give me some direction about how this is put together?

I can't tell how the logo is added to the header. Inspecting the markup generated it looks like it comes from Quad Menu, but I can't tell where in the UI Quad Menu handles adding the logo and links. (We have WordPress menus, JetMenus, QuadMenus...)

Would it be okay to take a copy of the site to install locally for testing? I need to try and see where the URL is stored and how it is output to whether it is feasible that the URL can be modified by WPML on secondary languages, and that will be easier if I'm not working on your production site.

Thanks.

Having examined the plugin code I can see that it makes no allowance for a multilingual setup (whether you were using WPML or something else), so the first thing I would do is to suggest you contact the plugin authors and invite them to join our compatibility programme so that we can work with them about making their plugin multilingual compatible. You can share this link with them: https://wpml.org/documentation/support/go-global-program/

I looked through some of their plugin source code to see if I could spot a filter that could be used as a workaround to modify the URL, but couldn't.

Which means the only solution I could find was to modify their plugin code itself. I'll share details below, but note that this means that every time you update the plugin the changes would be overwritten and you would need to re-apply them, hence why it is a good idea to encourage them to make their plugin multilingual ready.

The changes suggested below relate specifically to your use case, which is that the logo should link to the home page (in the current language). If at any time you changed the link to point somewhere other than the home page then it would need modifying.

Replace the current content of the file plugins/quadmenu/templates/logo.php with

<?php if ($url):

  $home = get_option('home');

  if ( $link == $home ) {
    $link = apply_filters( 'wpml_home_url', $home );
  } 

?>
  <a class="quadmenu-navbar-brand img" href="<?php echo esc_url($link); ?>"><?php printf('<img height="60" width="160" src="%1$s" alt="%2$s"/>', esc_url($url), esc_attr(get_bloginfo('name'))); ?></a>
<?php endif; ?>

(Note that we cannot provide support for custom code; I tested this on my local copy of your site, where it worked, but if you encounter problems with it you should contact quadmenu or a WordPress developer for further help.)

You can create different versions of Elementor templates to use on different languages (rather than simply translate templates to different languages) and I guess you could do the same with Elementor header templates.

See this document for how to do that: https://wpml.org/documentation/plugins-compatibility/elementor/#creating-different-elementor-templates-per-language
