i have site which is lately a domain.com but since i tried to change my hosting in this domain, changed its nameservers to my fatcow account and it turned out that it now has www.domain.com.
restoring it to this host work well except the posts.. viewing the www.domain.com looks good, yet when i tried to view www.domain.com/blogpost/ prompt me with 404 error
