I edited the apache httpd.conf file recently for the mod_rewrite to work. I don\'t know if this problem originated from that or not, but i\'m getting this problem from that
It is a SELinux blocking issue, Linux prevented httpd access. Here is the solution:
# restorecon '/var/www/html/wiki/index.php' # restorecon -R '/var/www/html/wiki/index.php' # /sbin/restorecon '/var/www/html/wiki/index.php'
