Hi,
I just found new bug (is it a bug?),
The wall on main page is allowing an user to insert HTML text into it,
let say the user want to insert an image to the wall, by using:
< img src = "http://site . com / image. jpg"/" >
but missing the ", it will cause whole main page to crash when the comment was added to the wall.
As an admin, the "delete" javascript button is missing too or it didn't display, and you can't delete that particular comment.
So, alternatively you have to go to your database and delete it manually from there.
