Problemas Idiomas Joomla 2.5  

Buenas tardes,
En el back-end de la web cuando voy a contenido desntro de la gestión de idiomas me aparece el siguiente errror:

Unknown column 'a.access' in 'on clause' SQL=SELECT a.*,ag.title AS access_level,l.home AS home FROM `jos_languages` AS a LEFT JOIN jos_viewlevels AS ag ON ag.id = a.access LEFT JOIN `jos_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 `jos_languages` AS a LEFT JOIN jos_viewlevels AS ag ON ag.id = a.access LEFT JOIN `jos_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 `jos_languages` AS a LEFT JOIN jos_viewlevels AS ag ON ag.id = a.access LEFT JOIN `jos_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

En inicio tenia instalado el joomla en inglés y luego he instalado el castellano, pero incluso desinstalando el castellano me muestra el error.

Os adjunto una captura de la imagen.
La versión de Joomla es 2.5.6

Saludos.
