One more time, from the beginning, because it does not look like you're following. I've already created a multi-lingual set of menus and menu items. This works perfectly fine. I was following the tutorial that you've sent. I don't have any complaints about this tutorial - it's perfect.
However, in your own template you are making me select a menu that shows on top (attachments). And this setting is in YOUR template and IT'S NOT language-dependent. That's my only problem. You introduced something that does not take language into account and you just need to fix that in your template.
As a summary. You don't need access to my backend. All you need to do is to read carefully what I have written, understand the problem and provide a fix to YOUR TEMPLATE.
