Every time I try to search for a file by name, (i put "marbella" as the search term in this instance, the file manager throws this error...

An exception occurred while executing 'SELECT f.fID, fv.fvDateAdded FROM Files f INNER JOIN FileVersions fv ON f.fID = fv.fID and fv.fvIsApproved = 1 LEFT JOIN FileSearchIndexAttributes fsi ON f.fID = fsi.fID LEFT JOIN Users u ON f.uID = u.uID WHERE (fv.fvFilename LIKE ?) OR (fv.fvDescription LIKE ?) OR (fv.fvTitle LIKE ?) OR (fv.fvTags LIKE ?) OR (uName = ?) OR (ak_image_tag LIKE ?) OR (ak_gallery_columns LIKE ?) OR (ak_internal_link_cid LIKE ?) OR (ak_external_link_url LIKE ?) OR (ak_link_type LIKE ?) ORDER BY fv.fvDateAdded desc, f.fID desc LIMIT 10' with params ["%marbella%", "%marbella%", "%marbella%", "%marbella%", "%marbella%", "%marbella%", "%marbella%", "%marbella%", "%marbella%", "%marbella%"]: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'ak_internal_link_cid' in 'where clause'

Any ideas what is wrong?
