Magento – Recent Viewed Products not showing

I am written the code for Recent Viewed Products on footer.phtml, but it's not showing.

my code is:

local.xml

<?xml version="1.0" encoding="UTF-8"?>

<layout>
    <default>

        <reference name="root">
            <action method="setTemplate">
                <template>page/2columns-left.phtml</template>
                <action method="setIsHandle">
                    <applied>1</applied>
                </action>
            </action>
        </reference>


        <!-- Remove callouts and rarely used stuff -->
        <remove name="right.poll"/>
        <remove name="right.permanent.callout"/>
        <remove name="left.permanent.callout"/>
        <remove name="paypal.partner.right.logo"/>
        <remove name="cart_sidebar"/>
 <reference name="footer">
            <block type="reports/product_viewed" name="product.recently.viewed" as="product_recently_viewed"
                                         template="reports/product_viewed.phtml"/>
        </reference>

    </default>

footer.phtml

<div class="block-content">
                <!--?php echo $this->getLayout()->createBlock('reports/product_viewed')->setTemplate('reports/‌​product_viewed.phtml')->toHtml(); ?-->
                <?php echo $this->getChildHtml('product_recently_viewed') ?>
            </div>

</div>
<?php endif; ?>
<?php
$queldorei_blocks = Mage::registry('queldorei_blocks');
if ( !$queldorei_blocks ) {
$queldorei_blocks = array();
} else {
    Mage::unregister('queldorei_blocks');
}
$queldorei_blocks['block_viewed'] = ob_get_clean();
Mage::register('queldorei_blocks', $queldorei_blocks);
