 * Whenever you perform an update to the ACF Fields, it throws some errors:
    ===

 * Thanks for the bug report!
 * Is this when you edit a post or when you edit the ACF custom fields?

 * I too have this error, when updating the Options page that is using a number 
   of ACF fields. All of it on the same lines.
 * Edit: To clarify it seems to work fine on other pages with ACF Fields. Only the
   Options page throws these errors at me.
