I have tried several ways to fix this problem but nothing I have tried has worked. I have a category called 'blog' and the problem is that when I click on that category link, I receive a 404 error and an additional 500 Internal Server Error.
I have tried deleting the category and renaming it something else 'blog stuff' and I still receive the same error. I have several categories, so I deleted a few of them to see if I could recreate 'blog'. This didn't work. I have created pages just to see if I could and I can.
I e-mailed Yahoo Tech support and they replied that they didn't support WordPress. I am thinking that it is a server problem since I also receive a 500 error.
I have also tired using different themes, even the default one, and I still have the missing category page.

Thanks for your time and advise in advance.
