Language loads after page refresh

Hi everyone,

I have a problem since my first installation of OC 2.0.1.1. Many times my language files don't load properly, I see BUTTON_CART etc... I noticed that it happens more when I come from another page and not when I write directly the URL in the browser. I have 2 languages and it happens both when the link is to an italian page and when it's to an english page. Never understood why this happens. I just know that if I refresh the page everything works well but after some days it happens again. The bad is that I cannot force the error because after a refresh everything goes well. I've tried to deactivate caching systems (JOURNAL2), I run on cloudflare and I tried in developer mode. I've read plenty of posts on language issues...But it continues to happen.

Do you have an idea?

thanks guys

Got a url for others to check?

ShoeTechnik.com . But as I said it doesn’t happen always

any idea?

Cant see the problem here, been through alot of categories and products changing the language at random times and all seems to work fine

Yes I know, it only happens sometime but I'm not able to understand under which conditions. I noticed it happens when I come from a link on other pages. It seems like it doesn't charge language file in time. Is it possible? Can I check it in some ways? Or maybe can it be something concerning with cache files?

I have a news... I discovered that google cache saves my website italian pages with the mistaken language. You can see it for example in this cache copy https://webcache.googleusercontent.com/ ... ent=safari

Moreover I discovered that html tag of this cache page starts with :
Practically is like it doesn't recognize the page language. Where can I modify this?
