my category order not working

Category Order works like a charm in my WP 3.2.1

can you put picture education of how works this plugin?

I just uploaded this plugin to /plugins/ directory and activated from Administration panel, after this you’ll see a new “Order Category” on the sidebar

I’m having same problem with Raindrops theme
“My Category Order” appears in Dashboard but when I save order nothing changes on the live site !!??

any ideas what the problem is ?
