Also, can you please verify that display_errors is set to On ? You can check this via the AdminCP, under Maintenance click View PHP Info.
If it's not set to On, please add
to your config.php file below <?php and then re-check that page. If the Local Value still says Off, please edit your php.ini file or use your control panel software to turn this display on.
It's most likely an error somewhere that's being suppressed by the system.
If it's not set to On, please add
PHP:
@ini_set('display_errors', true);
It's most likely an error somewhere that's being suppressed by the system.
