Prajjwal Byanju: just remove google authorship verification which you have done or talk with your programmer to remove authorship markup code from your site that may really works for you ;
Edwin Jonk: First this has nothing to do with authorship. Namely this error appears because of microformats that are setup in the template [1] (I guess WordPress).
Second, within GWT if you click on the "Page URL" there is a button "Test live data". Can you share that URL [2]?
[1] ;http://microformats.org/wiki/hentry#Entry_Author [2] It will be something like ;https://www.google.com/webmasters/tools/richsnippets?url=example.com/test.html
Chantal Brown: Is it this one? http://www.chantalbrownphotography.com/senior-portraits-plano-tx-hippie-styled/
Chantal Brown: Or this one? https://www.google.com/webmasters/tools/richsnippets?url=http://www.chantalbrownphotography.com/senior-portraits-plano-tx-hippie-styled/
Edwin Jonk: Not sure if this is helpful because you need to edit the WP template. Basically you are missing the author mention and link. ;
For (example) Twenty Fourteen the author byline is coming from the twentyfourteen_posted_on() function in inc/template-tags.php on line 107.
Edwin Jonk: Well you need to edit your theme... Let me ping +Tony McCreath ;because he is smart. He has a doctorate, as far as I know.
Tony McCreath: I know what the word doctorate means ;-)
I vote for +Edwin Jonk ;answer. It is probably some microformat markup that does not include an author parameter. Clicking on the error should provide more details on it. ;
Nothing to panic about but it may help in the future if it is added. ;
