 * I keep seeing the following errors when I try to test out the review plugin locally.
   I have not modified any part of the plugin and I only have 2 plugins running 
   on my local test install. Has this error been seen before and is this a configuration
   issue I would need to adjust in the settings or is this a plugin related issue?

   any rating items? Some existing rating entries may still use those a delwtedr
   rating item which could be the cause of the pronlem.
