If you're using CentOS it could be an issue with selinux. Check to see if selinux is enabled with 'sestatus'. If it is enabled, you can check to see if that is the issue (temporarily) using 'sudo setenforce 0'. If apache can serve the site, then you just need to change the context of the files recursively using 'sudo chcon -R -t httpd_sys_content_t' (you can check the existing context using 'ls -Z'.
Selinux may not be the issue, but it's worth checking on.
