Author Error Inside Google Structured Data Test

I receive this error when analyzing a review of my website: 'Missing required hCard 'author'' http://www.google.com/webmasters/tools/richsnippets?q=http%3A%2F%2Fwww.gamempire.it%2F

Solution 1:

author vcard has to be inside the hentry element http://microformats.org/wiki/hentry or you have to use the include pattern http://microformats.org/wiki/include-pattern, but I am not sure if it is supported by Google...

Solution 2:

you are declaring author a few times in that document...not sure if you want to use microformats, schema.org, or both?

you have markup for both, and one of the author classes is actually nested inside the other...so at the very least that is not correct....fix your nested authors first. if that doesn't resolve validation, come back and share. the solution(s) are relatively easy, but impossible to give you the correct one without knowing more.

Solution 3:

The solution is to create a new user mentioning him as Author in Admin Access, then open a page and go to screen option and select author. Now in the page check for author and update it with the new author user which you already created.
