For all user types.
It works perfectly on my development WAMP environment, but does not work on live server.
local.xml
<block type="reports/product_viewed" after="-" name="bottom.reports.product.viewed" as="recently_viewed" template="reports/product_viewed.phtml" />
When viewing the product page with template hints, the block exists at the bottom of the page, but with no content.
When I put a random html string into the product_viewed.phtml file, above everything, even this does not output - the phtml file is not even being called on the live server.
I would assume Mage_Reports_Block_Product_Viewed
is returning a blank collection - but I cannot find out why, please help!
