SOLVED!Problem installing new language

I hope there is the attachment, thanks a lot

In that "Content" tab one before last, do you have some filters set? If no maybe you will have to install language again.

I tried to install another language (French), I see that it is installed in the first and in the second tab where there are also English and Italian language, but in the third tab (language contents) there is only English and not more. I don't understand why.

Here is some guy step-by-step guide:

just in case you did not do it that way.
If all ok, then you need to ask for help on joomla forum because this is as far as we go since we sell templates.

FINALLY SOLVED! Languages had been automatic installed in front-end and in back-end but you have to set manually the language in the tab Content Language, you have to create a new one, set parameters and save it. After you'll have to create you menus, I read this to create two menus (one for Italian and one for English) www.joomla.it/mediawiki/index.php/Joomla...Gestione_multilingua
Thanks to all, have a good day
