Hello, I have an issue with facebook Like/Share on some of my threads. Facebook can get information (title, description, image) on some threads, but some they can not. For example, When I like or share this thread with Facebook, they can not get info, just only url posted: http://www.tinhte.vn/threads/1427627/ But if I add a random parameter ending, ie, http://www.tinhte.vn/threads/1427627/?abc they can get. And this one works properly: http://www.tinhte.vn/threads/1427731/ I don't why. All threads are public & have same open-graph properties. Can anyone help me? Thank you!
