Messages on the wall

Hi! I have received a message from Debbie and tried to reply, but I seem to be unable to post a message on her wall. I don’t understand. It has never happened before. Is there something wrong with my account?

You know, I’ve seen this too. It happens occasionally that I can’t click the button to write on someone’s wall. The problem eventually goes away, I don’t know how or why.

It should be working properly. As long as you type text into the box, the “Post” button should be clickable. What browser are you using? Also, have you tried refreshing the page (control + F5)?
