How about if I just give you access to my site as I really do not remember everything I changed. The only other thing I did was removing the option to add comments as I was getting a lot of spam.
I just created an account called budduke on your site if you can make me an admin so I can see what is happening in the admin area for creating categories.
Also, PM me some FTP info so I can look at your files. I will see if I can work it in the next couple of days.
Regarding Spam,
My site was also getting hit with spam in the comments. It seemed they created a script that created a new user and then started posting comments all over the place. Easy to delete when I sorted the comments by date/time. Became a nusance in the last couple of weeks so I changed the new user registration to "admin approval" and posted a message on my main page to tell real people to e-mail me after they register so I know they are a real person and that seems to have stopped all the spam so far. I do get 7 or 8 activation notices a day but I just go in a delete the accounts. I may try changing over to recaptcha on the comments to see if that does anything but you would think they would have something better to do then post garbage on other peoples sites.
