Using Weaver II theme on website at http://www.safeharbourtherapy.com. Installed Unique Headers plugin last week.
It is not displaying correct header images for categories.
This URL should display the same image as http://safeharbourtherapy.com/2014/02/12/research-series-verapamil-2/
On some pages there is no header displaying.
Tested on Firefox.
Any ideas why this is happening or how to fix it?
