Milhko,
There's probably some system-level problem on your installation
preventing the PHP to run properly. Please change the
/path-to-eventum/config.inc.php file on the following lines:
ini_set("display_errors", 0);
error_reporting(0);
To this:
ini_set("display_errors", 1);
error_reporting(E_ALL);
Try to load Eventum again and send me any error messages that you might
receive. If you still don't receive any error messages, please check the
permissions on your eventum directory and files contained within it.
Hope that helps.
