Okay, long story short, and this is weird:
My configuration: Apache, PHP, Mysql, WordPress
My installation went pretty well actually, everything is fine.
Question is when I wrote a post, why it didn't create directories under my wordpress directory.
Like this IP/wordpress/2008/01/22/second-post/
I checked out the wordpress directory, the 2008, 01 , 22 directories weren't created at all, that's why when I go to that link, it displays 404. I have actually chmod 777 on that wordpress directory, so I don't think it's the problem of writable or not.
Any thoughts, everyone?
