Today Installed XPanel on dkmhosting.com
Server was Cpanel box with Xpanel already installed. There was some errors with config.pm and need to make few slight changes in cgi scripts and httpd.conf
php_admin_value is not working in httpd.conf or xp_httpd.conf, also phpmyadmin is not working in http auth_mod. Recompiling apache with /scripts/easyapache solved the problems with PHP.
