WordPress database error

My server host has restored my database today yet I still get these messages at the start of each post. They said they can’t help any more. Can anyone suggest what the problem is and how I can resolve it?

WordPress database error: [Unknown column ‘instances.raw_url’ in ‘field list’]
SELECT instances.raw_url FROM wp_blc_instances AS instances JOIN wp_blc_links AS links ON instances.link_id = links.link_id WHERE instances.container_type = ‘post’ AND instances.container_id = 2982 AND links.broken = 1 AND parser_type = ‘link’

Thanks
