Running version 3.9.16263 of easyblog on a Joomla! 2.5.24 site, and getting a lot of structured data errors in correlation with the itemprop="author" parameter not displaying the "Name". Here is just one of the test from Google for one of the blog post. This error shows on any blog page that shows an avatar, and for every avatar displayed. I apologize I cannot provide FTP or backend access since this is not my site, but my clients. I do have access to both the backend and FTP, and can package files to upload here for you to look at if you like.
