 * I received this error message in my debug file this morning and wanted to know
   how bad of an error this could turn out to be.
    WordPress database error Table‘
   wordpress828.wp__blc_instances’ doesn’t exist for query SELECT instance_id FROM
   wp__blc_instances WHERE container_id = 9572 AND container_type = ‘post’ made 
   by wp_trash_post, wp_update_post, wp_insert_post, wp_transition_post_status, 
   do_action(‘trash_post’), WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array,
   blcPostTypeOverlord->post_deleted
 * My website has not crashed or anything like that. I just want to stay on top 
   of my debug and know what this error message means so when my boss asks me about
   I have a good idea of why this happened.

 * Hmmm, do you have a plugin with a Post Type Overlord? Does it trash posts?
    If
   not, could be a SQL injection somewhere, which is a sign of a vulnerability.

 * I do not have a plugin with post type overlord to my knowledge.
