Fatal error: Uncaught Error: Function name must be a string app\code\core\Mage\Core\Model\Layout.php:555

It happens because in PHP 7 you need to clarify that you are going to call the $callback variable as a method (function). So, the original line of the code looks like the following (file app/code/core/Mage/Core/Model/Layout.php):

$out .= $this->getBlock($callback[0])->$callback[1]();

In order to make it work on the latest PHP version we need to replace this piece of code by this one:

$out .= $this->getBlock($callback[0])->{$callback[1]}();

Assuming that you want to add my_custom_input_field to your order and add a field to your admin create order page (to add the field to the frontend you just need to add the input field to the front template and double check the observer)

In /app/code/local/MageIgniter/CustomOrderStatus/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <MageIgniter_CustomOrderStatus>
            <version>1.1</version>
