Hello,
I just updated the plugin today (march 26, 2014). I later began to update some field groups. I refreshed the custom post type’s admin interface to see the new fields but all the fields for the custom post type were gone.
I investigated thinking it was a plugin conflict. Then I seen the rules had been changed for the field group. They were no longer pointing to the custom post type, but rather to a regular post.
I clicked the drop down menu to select the custom post type and then I clicked update. I noticed that it didn’t change or save to the correct post type, just the default “post”.
It seems to stay on the default “post”. What can I do? I continually tried to change the drop menu, but it won’t save the changes to the field rules.
