All I did was add a couple of extra custom fields. Didn't change anything else. As soon as I clicked update, all posts are now gone, but they are still in database as it is still being pulled into the page, I just can't see them in the backend. Please advise?
It is mostly related to the post type slug. You can access the database, table wp_posts check the column post_type if it matches the slug in Meta Box > Post Types > Edit the post type.
