Not possible to click on smileys

Have just installed image_upload-1.2.1 and it works great.
But when I want to answer a post or make a new topic the smileys
doesnt work. They are all there but when you try to click on then nothing happens.
And all the smiles that are in all the post's since before are still there.
There was a lot of php-files that was modified, I think that is were  the problem is, but where???

Edit: Found the problem
This was missing in the post.php at one place.
