Hi.
Any progress on this issue?
I’m having exactly the same problem. I’ve got a really simple setup as per the instructions here: http://www.advancedcustomfields.com/resources/tutorials/creating-a-front-end-form/
Just pulling all the fields as is from a particular field group.
The form is working perfectly except for the relationship field group. The wheel just keeps spinning and nothing loads in the box.
If I change the field type to “Post Object” it loads the values perfectly.
Looks like a problem with the AJAX loading in the front-end form. In the backend add/edit post form, the same relationship field works perfectly.
Any ideas?
Thanks
