Hello, sorry for yet more questions.
I have another problem that I think depends on the template: k2 article of some of the terms are not translated (attach print screen 1).
I state that I have installed the version 2.6.7 and downloaded the files of the Italian language.

I think it depends on the template because installing everything on a default template of joomla, everything works ok

Can you send me your site url ?

Regards
