 * Hi,
 * When I re-save a post with ACF fields (input data generated via WP User Frontend
   form) it goes into a `Uncaught TypeError` for `explode()` in file `class-field-
   checkbox.php` on line 184.
 * Any idea what this is? All I did was via the backend update a field instead via
   the frontend.
 * With thanks,
    Demian

 * [@demian85](https://wordpress.org/support/users/demian85/) Do you have any empty
   value of the checkbox field with the associate WPUF post form? Please check that
   one and resave.
 * Please reach our native support ([https://wedevs.com/contact](https://wedevs.com/contact)
   or support[at]wedevs.com) if you are still struggling with the issue.
    Thanks.
