 * Hello [@shirtguy72](https://wordpress.org/support/users/shirtguy72/),
 * Thank you for reaching out to us!
    That error seems to be from a different plugin:
   [https://wordpress.org/plugins/post-types-order/](https://wordpress.org/plugins/post-types-order/)
 * You would need to reach out to their support team regarding this.
 * Warmly,
    Mihaela
