 * Getting an error when an existing post type is mapped but saved with out any 
   of the fields added. This breaks the field select functionality, requiring the
   post mapping to be deleted & recreated:
 * `Warning: in_array() expects parameter 2 to be array, null given in \wp-content\
   plugins\post-my-contact-form-7\includes\class-cf7-2-post-factory.php on line 
   704`

 * Hi [@michent1](https://wordpress.org/support/users/michent1/),
 * thanks for reporting this error, much appreciated, however could you tell me 
   what you mean by ‘saved with out any of the fields added’, do you mean custom
   meta-fields?
 * > This breaks the field select functionality, requiring the post mapping to be
   > deleted & recreated
 * Did you try to set the status of the mapping back to draft (read the [2nd but last FAQ](https://wordpress.org/plugins/post-my-contact-form-7/#faq-header))
   instead of deleting/recreating it?
