Breadcrumbs wrong, changing language dont stay on same page

Hello,
After I turned on some of the template Advanced settings my site is not working fine.
The biggest problems are with Breadcrumbs and language. Now I turned all of them off but its still bad.

The breadcrumbs start getting random article name. Then when I clear the cache its deleted and not showing anything at all. Then after browsing 3-4 pages it gets another article name.

Somethings happened and changing languages dont work as is used to. When I change the language it took me to the root of the K2 category and when I'm in the K2 item the breadcrumb is showing wrong path, specific item.
See here: http://www.luxintegra.mk/en/kolumni .
Its the root of the category but in the Breadcrumbs its showing title from another item in same category. Even if clicking on another item its not changing it.

Also, in articles some of the language strings start showing instead of the translation.

Also the facebook addon in articles don't get its language correct.

Can you please take a look on it.

Thanks,
Gorast

Hi,
it was the Cache. When I turn Conservative caching everything goes wrong. How can I use website caching but still have correct website?

Thanks,
