First, sorry for my bad English.
I have a problem after installing Yoast SEO plugin, when i post a link on Google+, the title is duplicated like this: https://lh6.googleusercontent.com/-YqYm8cks7KQ/Tt94iCEArqI/AAAAAAAABR0/VF9ZeFLxcUc/s640/2011-12-07_213011.jpg
And after that, i remove this SEO plugin but the problem still have existed. I even deactived all the other SEO plugin, and remove the title tag on header.php but it's still useless.
Please help me, how can i solve this problem?
