Disabled all plugins and then re enabled them one at a time.  Just going through that process cleared the problem.

WordPress version 4.6

same problem here can not comment

Hello Rahul, I’m using ver 2.4.8 of Anspress. Google Webmaster is still display error missing of “Author”, “Updated” and “Entry-title”. I don’t think this issue has been fixed. Now how about solution for that? Please help. Thanks a lot.

What was the solution to this? I’m facing the same issue!

Still no succes

Switch to PHP 5.5 or later (7 preferable).

Still a problem@rahul

WordPress has several such security holes. Try this one on your site: www.yourwebsite.com/?author=1 and you will see the name (replace the number to 2,3,4,5,6 and see all the usernames). AND #1 is ALWAYS the Admin. Go figure.
