Magento Custom Admin Module gives 404 error

Question

I have been trying to get an Admin module running for updating some prices. But I keep getting a 404 error. I followed this tutorial: https://magento2.atlassian.net/wiki/spaces/m1wiki/pages/14024903/Create+a+custom+module+with+a+custom+database+table

Answer 1

<menu>
            <priceupdate module="priceupdate">
                <title>PriceUpdate</title>
                <sort_order>71</sort_order>              
                <children>
                    <items module="priceupdate">
                        <title>Manage Items</title>
                        <sort_order>0</sort_order>
                        <action>priceupdate/adminhtml_priceupdate</action>
                    </items>
                </children>
            </priceupdate>
        </menu>

it should be

<menu>
        <priceupdate module="priceupdate">
            <title>PriceUpdate</title>
            <sort_order>71</sort_order>              
            <children>
                <items module="priceupdate">
                    <title>Manage Items</title>
                    <sort_order>0</sort_order>
                    <action>adminhtml_priceupdate/priceupdate</action>
                </items>
            </children>
        </priceupdate>
    </menu>
