Sorry, maybe I didn't explain it right. I didn't import any of the new styles. I had 15 styles before. One for each of the 14 forums and one for the cfrm.

Before the upgrade, I removed the ability for anyone to switch styles, but each forum had a selected stylesheet with it's own logo and some minor differences like removing the side panels, etc. And it all worked out.

Now, only the default style (in this case the cfrm default one) shows for each forum even though I have selected a different style in the cp for each forum.
