Magento 1.9 – Get All Recently Viewed Product IDs

HomTom just change the block name name="right.reports.product.viewed" fro this code

<block type="reports/product_viewed" name="right.reports.product.viewed" as="recently_viewed" template="reports/product_viewed.phtml" /> of product page .

As two blocks have same name to it.<default> handler is working also on all frontend page

Default handler is also remove Recently Viewed Products from product page view

So,change

<catalog_product_view translate="label">    
    <reference name="content">         
        <block type="reports/product_viewed" name="right.reports.onlyproduct.viewed" as="recently_viewed" template="reports/product_viewed.phtml" />     
    </reference> 
</catalog_product_view>

name="right.reports.product.viewed" change to name="right.reports.onlyproduct.viewed"

You could try this solution from: https://stackoverflow.com/questions/15682483/how-to-get-recently-view-product-for-guest-user-in-magento

Override: class Mage_Reports_Block_Product_Viewed

Add this function:

   protected function _toHtml() {

/*   if ($this->_hasViewedProductsBefore() === false) {
    return '';
} */

$this->setDisplayMinimalPrice('1');
$collection = $this->_getRecentProductsCollection();

$hasProducts = (bool)count($collection);
//        if (is_null($this->_hasViewedProductsBefore())) {
//           Mage::getSingleton('reports/session')->setData('viewed_products', $hasProducts);
//        }
if ($hasProducts) {
    $this->setRecentlyViewedProducts($collection);
}

return parent::_toHtml();
}
