The item is set to insert ‘Frame Contents’, but has no text boxes

This is displayed because the ‘Insert’ attribute is set to ‘Frame Contents’ on an object that is not a text box. The most common reason for this is that it has been applied to a group of objects. This group of objects would need to be ungrouped and then anchored within a text box; the attribute can then be applied to the text box.
