SOLVED!Problem installing new language

hello, I downloaded some days ago this template, I saw that is only in English, so I installed Italian language. Admin control panel changed from Englis to Italian without problem, but when I click on language management and after on language contents I have this problem:
"500 - Si è verificato un errore.
Unknown column 'a.access' in 'on clause' SQL=SELECT a.*,ag.title AS access_level,l.home AS home FROM `wnc09_languages` AS a LEFT JOIN wnc09_viewlevels AS ag ON ag.id = a.access LEFT JOIN `wnc09_menu` AS l ON l.language = a.lang_code AND l.home=1 AND l.language <> '*' WHERE (a.published IN (0, 1)) ORDER BY a.title asc Unknown column 'a.access' in 'on clause' SQL=SELECT a.*,ag.title AS access_level,l.home AS home FROM `wnc09_languages` AS a LEFT JOIN wnc09_viewlevels AS ag ON ag.id = a.access LEFT JOIN `wnc09_menu` AS l ON l.language = a.lang_code AND l.home=1 AND l.language <> '*' WHERE (a.published IN (0, 1)) ORDER BY a.title asc Unknown column 'a.access' in 'on clause' SQL=SELECT a.*,ag.title AS access_level,l.home AS home FROM `wnc09_languages` AS a LEFT JOIN wnc09_viewlevels AS ag ON ag.id = a.access LEFT JOIN `wnc09_menu` AS l ON l.language = a.lang_code AND l.home=1 AND l.language <> '*' WHERE (a.published IN (0, 1)) ORDER BY a.title asc"
How can I fix it? Have I to do another method to install another language? Can you help me, please? thanks in advance

Do to Extension Manager "Database" tab and check is there any button saying something like "click here to fix database" if yes click on it

Thank you, now there is no longer that error. I clicked on contents language and I read English, while in Installed Site there are both English and Italian. I tried to write a new article and I can select only English or All Languages but not Italian

Do you have it defined in language manager?

I attached my screenshot so I can explain

better, thanks
