Hi I have a site labonieu.wordpress.com. If you go to the blogs section you will see that I have use post grid for a grid layout. But for 2 posts I can see 2 thumbnails each which are same. Also I cannot see the excerpt text completely. Strange, because I was able to see it yesterday. I reached out WP guys and they have asked me to get help from you to fix the thumbnail issue.
