Hm, the error messages are pretty ambiguous as it doesn't tell us which item scope it's generating errors on as almost every item scope has the attribute "name". I have applied some fixes but not sure if this is the problem, can you try monitoring this and see if the errors are gone?
Hm, that's not good. Is the errors appearing as it was previously? Could we wait for a couple of days more and see just in case it's being cached by Google?
I just added another block of code, can you monitor this? To be honest with you, this is worst than finding the needle in the haystack because Google Rich Snippet tool is not reporting any errors and there are no way for us to know what that error message is all about on GWMT
