This code supposes to output therecently viewed productson the category page or product page (by inserting the roadrunner email code in .phtml files). and this has been always working for me on my Magento sites. However, I have experienced that for one site (Magento 22.214.171.124), this code isn't working at all. and for this site, thewidget to show recently viewed product doesn't work either.
Any ideas what can cause the "recently viewed products" isn't working?
