But I'm having a hell of a time.

What should I do to do this? The phpbb version is 2.0.7 and the phpnuke bb is 2.0.10, I found a converter from hcor.net, but once it is done it still indicates on phpnuke bb that there are no forums in the forum..

Bit silly but have u actualy made a forum section in there I.E go to admin panel>forums>forum admin manigment go in manigment create forum see if it will display anything nut sure if u have done that yeat but see if that works :-) Good Luck Boris

That works, but I was hoping that I could just get the database transferred.. or do I have to make the categories for the posts to show up?

well I dont know any other way but thats how I done it my self and every time u make the forum section that will be empty untill u add a new post in there :-D Im only lerning php my self so Im not really good with this side of things Im photoshop artist ask me question on that subject :-D any way glad that that works m8 :-) good luck Boris
