I deleted my nuke database and completely reinstalled 6.5. I put smartDark's "forums" folder in my themes/Mytheme/ folder. I did not change anything except for that.

The only problem I have now is that the images are pointed to the wrong directory. They point to:

not

Where are these default paths saved?

I know this was a completely frustrating thing to deal with and I am thankful that you took the time to help me out here.
