Error 500 - Language Content

Hi,
just ordered Corporate-Template and installed Joomla according to install-instruction PDF. Everything looks fine, howerver, I am not able to setup second/another language: Menu - Extesions - Language Manager - Content. I receive an error 500:

"Unknown column 'a.access' in 'on clause' SQL=SELECT a.*,ag.title AS access_level,l.home AS home FROM `hw3tm_languages` AS a LEFT JOIN hw3tm_viewlevels AS ag ON ag.id = a.access LEFT JOIN `hw3tm_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 `hw3tm_languages` AS a LEFT JOIN hw3tm_viewlevels AS ag ON ag.id = a.access LEFT JOIN `hw3tm_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 `hw3tm_languages` AS a LEFT JOIN hw3tm_viewlevels AS ag ON ag.id = a.access LEFT JOIN `hw3tm_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"

Please, can you advice?

GO to extension manager , "Database" tab. Check if there is some button saying something like "click here to fix database" if yes click on it

Thank you.

What is component "com_falang" ?

Multiple language module

The errors you listed above are related to component "com_falang". Therefore, you should ask for support from the component developers.

Thanks
