Access Denied Error in Admin Panel Custom Moduel

Question

I am getting access denied error for 3 Tabs in admin panel.

Custom module config is under

<acl>
        <resources>
            <admin>
                <children>
                    <vendor>
                        <title>Vendor</title>
                        <children>                                
                            <orders>
                                <title>Orders</title>
                            </orders>
                            <transaction>
                                <title>Transactions</title>
                            </transaction>
                            <review>
                                <title>Reviews</title>
                            </review>
                        </children>
                    </vendor>
                    <system>
                        <children>
                            <config>

Log out and log back in. If you just installed the module and have not yet logged out, this is expected behavior.
