Hello,
The JA Tour template includes a script that centers the logo within the megamenu on large screens. However, the script only targets the menu with the ID #t4-megamenu-mainmenu, while your multilingual menus use different IDs. This is why the logo was not centered for those menus.
I’ve updated the jQuery script to support the additional menu IDs.
Please download the attached zip file, unzip it, and copy the file to:
[root-joomla-site]/templates/ja_tour/local/js/template.js
If the local/js folder does not exist yet, you can create it manually.
Then clear browser's caches & cookies.
Regards,
Heinz
