Hi Otto42,
This is a cPanel WHM server, and the only change from before is Apache 1.3 has been upgraded to Apache 2.2
I have searched around httpd.conf – there is no deny all at all. Only in the .htaccess section of httpd.conf
The server is also running PHPsuEXEC so all files must be owned/group by the user. I already tried overriding the permissions and the problem still exists.
Customer tried to re-install Copperleaf plugin and WordPress and the problem still persist. With this plugin only.
Other sites on the server work fine.
