I figured out what the problem is. Your YooTheme joomla template is guilty about this language problem.
I found where this en_US sdk file gets loaded, it is inside this JS file:
katuma.it/media/template/gzip.php?theme-869a4988.js
That is the line that force your website loads the en_US sdk.
You have to find where this line comes from. Since this javascript file is GZIP, it impossible to find its original source. First, disable the GZIP from the Template Settings, and all the JS files will be loaded individually. Then carefully search for this line in each JS file, find it and change
en_US to
it_IT.. Or maybe there is a dropdown selection in the template manager, where you can change the language quickly. If you fix this manually through JS file, or can't find a language selection in the template manager backend; you may try to contact YooTheme support department and ask for help from them.
