Sounds like the error reporting may be turned off and there is a PHP error. This is common with some hosts as it masks information about your system.

If you can read the error_log file for apache/httpd ( generally in /var/log/httpd/error_log but you will need sudo/root permission ), scroll to the last message and see what it is. You can do that if you have SSH access to the server and know your command line foo.

Next thing is to temporarily, only temporarily, set error reporting to all:

Code:

<?php
error_reporting(E_ALL);
?>

You can use that method in index.php or alternatively set it to E_ALL in php.ini, whatever floats your boat.

Check the error and debug. Also other things to cross check are PHP versions on your local test server and the host. If the host has an older version you may come across some version issues depending on how old it is.
