  • That depends on the field type. You will see problems on the front of the site. For basic fields that store text in the database there will not be a problem. But for a field like a post object field for example, this stores a post ID. ACF will not know what to do with the ID value and will return an integer instead of a post object. Any field that does not store a text value will not work on the front end.
