Hello,
I found a lot of errors like these in the log file:
WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 1 for query UPDATE wp_posts SET post_parent=35796 WHERE post_parent=0 AND ID IN () made by edit_post, wp_update_post, wp_insert_post, do_action('save_post_activity'), WP_Hook->do_action, WP_Hook->apply_filters, RW_Meta_Box->save_post, array_map, RW_Meta_Box->save_field, RWMB_Field::process_value, RWMB_Field::call, RWMB_Media_Field::value
I think it happens when editing and publishing custom posts, but everything seems to work fine. What does this error mean? It does not mention any post type or field ID.
Kind regards,
Arno
