I tried the above and it did not work.
1. I thought the "supercat" was for the main categories and the "category" was the subcategory. Please read your previous instructions on which to list the main categories under. I attempted both ways anyhow.
2. It did not create files in the auctiondata directory. Does it make a difference whether the old folders were there from the previous categories?
3. I changed the permissions on the category folders to 777 as instructed. I made a directory for each just as a test after they didn't show up in the auctiondata directory.
I can't believe that changing categores is this complicated. We must be missing something. Not only does it not just work the entire page won't come up although I have the original codes.
