Model File:-

<?php

class Unirgy_SimpleUp_Model_Module extends Mage_Core_Model_Abstract
{
    protected function _construct()
    {
        $this->_init('usimpleup/module');
    }
}
?>

Answer 1

you have to Check your module "Unirgy_SimpleUp".

This module location will be app/code/local/Unirgy/SimpleUp or app/code/community/Unirgy/SimpleUp.

Need to replace "usimpleup" with "simpleup" into your config.xml file.

also, replace below code into your Module.php file

protected function _construct() { $this->_init('simpleup/module'); }

Answer 2

Try this:

Your model files and extension folder structure should be this:

app/code/{{code pool}}/Unirgy/SimpleUp/

You can continue with usimpleup/module model calling.
