congiothoang and Warwick,
I think I found the problem that might be causing anything to display on the Recently View menu box. I was viewing congiothoang's source code to see what might be causing the problem and I noticed that the include recently_viewed file is called before the product.tpl is called. The product.tpl has the javascript code that is required for the recently_viewed to display the recently viewed product. Therefore, nothing is showing up.
So in order for the Recently Viewed mod to work, the menu box has to be located on the right side or at the bottom of the product page like in Qdox post #36. This mod will not work if it's located on the left side with the other menu boxes.
My sincere apology for those who had problems when installing this mod on the left side of their webpage.
Try it on the right side or on the bottom and it should work.
I'll update post #1 to reflect this change.
On another note, I installed XC SEO and it's working perfectly with this mod.
I hope this fixes your problems.
