Order View Display Nothing

Question

I didn't know hat happen to my magento site but it seems that the order view is not working. What could be the possible reason for this? Please help me.

Answer 1

Seems like an error in PHP

Magento Mode

Go to index.php and modify:

if (isset($_SERVER['MAGE_IS_DEVELOPER_MODE'])) {
    Mage::setIsDeveloperMode(true);
}

by

#if (isset($_SERVER['MAGE_IS_DEVELOPER_MODE'])) {
    Mage::setIsDeveloperMode(true);
#}

And

#ini_set('display_errors', 1);

by

ini_set('display_errors', 1);

PHP Mode

This always works for me:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

However, this doesn't make PHP to show parse errors - the only way to show those errors is to modify your php.ini with this line:

display_errors = on

When you see the error go to url referred by @gopal-patel : magento order view information is blank page
