Categories and tags don't work


#1

Hello all !
Perhaps you can help me?..

I’ve made some categories on my site. But the all categories and the all tag pages lead to the 404 page. Have I done something wrong? How I can fix this problem?

One more question:
Where can I find and hide (delete) autor of the post? Only on the main page. http://clip2net.com/s/3l3G6mL

Thank you.
