Error: Mage registry key “_singleton/mage_gextorshop/observer” already exists

Question

(Sorry if my english is bad, but is not my language)

My Magento version is 1.9.3.8

I tried to solved this error whit this in SSH:

php -f shell/compiler.php disable
php -f shell/compiler.php clear
php -f shell/compiler.php compile

But didnt work (with compile, and without it).

This is my config.xml:

<?xml version="1.0"?>
<config>
    <modules>
        <Mage_Gextorshop>
            <version>0.0.1</version>
        </Mage_Gextorshop>
    </modules>
    <global>
        <models>
            <mage_gextorshop>
                <class>Mage_GextorShop_Model</class>
            </mage_gextorshop>
        </models>
                <helpers>
                        <mage_gextorshop>
                                <class>mage_gextorshop_Helper</class>
                        </mage_gextorshop>
                </helpers>
        <events>
            <sales_order_save_commit_after>
                <observers>
                    <mage_gextorshop>
                        <class>mage_gextorshop/observer</class>
                        <method>logUpdate</method>
                        <type>singleton</type>
                    </mage_gextorshop>
                </observers>
            </sales_order_save_commit_after>
        </events>
    </global>
</config>

In LocalHost had the same problem and when I used the SSH commands, solved it. Also I uninstalled the custom module, used SSH commands and installed again the module but error continue.

Other similar questions that I found didnt help me.

Try this:

<?xml version="1.0"?>

    <modules>
        <Mage_Gextorshop>
            <version>0.0.1</version>

    </modules>
    <global>
        <models>
            <mage_gextorshop>
                <class>Mage_GextorShop_Model</class>
            </mage_gextorshop>
        </models>
                <helpers>
                        <mage_gextorshop>
