Original Code 

<h3 class='post-title entry-title' itemprop='name'>

Finally: 

<h3 class='post-title entry-title' itemprop='name'>

<h3 class='post-title entry-title' itemprop='headline'>

If you think it is very easy to do than you may can it directly. Make sure after editing the code looks like following"
