I cannot change my profile through the forum profile information account editor! The button that says "change profile" is not clickable! Whats happening? AGH!
I'd try viewing the button in a different place on the forum. Sometimes links become clickable again that way.
There are certain features (objects) on the right-side frame of the forum that, due to HTML/XML limitations, block access to certain buttons in the same row. Try doing what MagmarFire suggested. If that doesn't work, just PM me with what you want changed and I can do it for you.
You could always change the theme. I have that silver and blue theme that was used while KP was fixing the forums a while back. Personally, I have found it better than the default layout.
