Does anyone know why I can't post in any of the các diễn đàn hoặc on people's walls?

xin chào there!
I know someone else here with the same problem..they can;t post on anyone's wall!
sometimes I can't post on people's wall.....it happens to me when I am on the Internet Explorer...Google Chrome rarely does that to me....
if bạn are using Internet Explorer...try Chrome!
if that doesn't work, I'm afraid I can't help!
good luck and have a nice day!
