Hi, i used this plugin to add meta tag og to website, but after activated, in my sources code i see the line :
this page doesn't show a meta description because it doesn't have one, either write it for this page specifically or go into the SEO.
When i share link to facebook, it doesn't show thumb, title, description... :( I try to share this link in Google plus and other social website, it's showing full thumb, title,... I dont know why facebook can not get meta tag from my site.
I do not use other SEO plugin, i used hueman theme wordpress. This is my url: http://www.sforum.vn/schannel-mo-hop-loa-di-dong-beatspill-xl-cellphones/
