I checked your files but found nothing wrong in them.
My gues now is that you forgot to upload one of the files or, in some cases it just did not get overwritten by your ftp program.
Try renaming the files on your server and re upload the new editted files again and see if that helped.
If that does not help, you could considder installing "Journal or Support Forums", which in fact can do the same and more.
You can find that version at my modforum in topic: http://www.detecties.com/modforum/viewtopic.php?t=54
