How do Ты post a comment.

It sounds like a temporary glitch, it's happened to me before. Try copying the message Ты want to post, refreshing the page, pasting the message and seeing if it posts then. That's worked for me.

That might be a setting for that user. I'm p sure Ты can change your Профиль settings so only certain people или no one can post on your wall.

You're not alone!
I've had that problem since I got a new computer.
It won't allow me to give Благодарности или post on anyone's Стена - including my own.
A few people have suggested switching browsers, but Fanpop seems to be the only place that's affected, so I'm hesitant in doing that. I'm hoping that it's just some kind of Fanpop glitch, and that it will eventually be remedied.
