مشکل با صفحه عنوان در صفحه انتخاب زبان

با سلام
من در پنل مدیریتی وقتی به قسمت انتخاب زبان میرم و بعد به صفحه عنوان میخوام برم با پیغام زیر روبرو می شم :

Unknown column 'a.access' in 'on clause' SQL=SELECT a.*,ag.title AS access_level,l.home AS home FROM `nash_languages` AS a LEFT JOIN nash_viewlevels AS ag ON ag.id = a.access LEFT JOIN `nash_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 `nash_languages` AS a LEFT JOIN nash_viewlevels AS ag ON ag.id = a.access LEFT JOIN `nash_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 LIMIT 0, 20 Unknown column 'a.access' in 'on clause' SQL=SELECT a.*,ag.title AS access_level,l.home AS home FROM `nash_languages` AS a LEFT JOIN nash_viewlevels AS ag ON ag.id = a.access LEFT JOIN `nash_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

من زبان اضافی نصب نکردم پیش فرض خودش فارسی و انگلیسی داشت که فارسی پیش فرض بود.

از جوملا 2.5.4 استفاده میکنم.
ممنون از راهنمایی دوستان
