Just 7? Is that < 7.1.0 or >= 7.1.0,
although if your trying to get the count of a repeater then is should be returning an number.
get_sub_field() does not take a post ID argument. This may sound like a stupid question, but are you sure it’s a repeater?
The reason I’m asking these questions is that the only reason that this should be getting a false value is that there is actually a value in the database and for some reason it’s being interpreted as false rather than whatever is store in the db.
