[WPMOODS] in a page and the output is
The widget works but displays a mood of "Mood : So Bad (0.0/4)"
and this: "Last updated : 12/31/1969 17:00:00" which is definitely not the right date. Of course it was never updated because there is no way to set your mood. I don't see the "Add a mood" admin widget anywhere that looks like the screenshot you have provided.
