I have been here a long time and I do not recall a version v 18.104.22.168.
2003 should have beel like version 5.X-6.x
Could be one of the old free test versions? that got upgraded to a full license.
But anyway if it is indeed ubbclassic it probably needs to be upgraded twice once to the last ubb classic version then to ubbthreads.
What is the url you have for the site. Even if it is now broken..
That may give a clue to what it is.
