Thank you this appears to have sorted out part of the problem.
I am dealing with authorship.
Another error I am getting is as follows:-
Error: No rich snippet will be generated for this data, because it appears to include multiple aggregate reviews of many items, instead of a single aggregate review of one item
Hm, this is odd because I remember fixing this in one of the later versions. Can you please provide me with the link to the page so that I can run some tests with the authorship testing tool?
