[Plugin: GD Star Rating] Thumb Rating not showing!

Maybe you have some cache plugin?

Yey, I did, it’s resolved.

I’m not using cache plugins just wordpress 2.9.2 and last of gdstar rating on https://www.partyefun.it/scherzi and stars are not showed up

I solved with these info:
Plugin is not showing rating stars or rating widgets after update, or all stars and thumbs have disappeared, and there is nothing in stars/thumbs selection lists.

Check all plugin settings and plugins widgets settings after update and save them. If graphics is gone, try rebuilding stars and thumbs sets: go to plugin Tools -> tab Graphics -> Rescan.

Yes, that’s one of the things in the FAQ included with plugin.
