How to switch Latest Product and Best Seller

How to switch Latest Product and Best Seller in 1.4.5?

For bestsellers on the homepage: http://forum.opencart.com/viewtopic.php ... t+products
For latest products in the side, I have a free module for that:

Hi Qphoria,

I download this free module you have in your webpage but i get an error when I install it, even before I ennable it:

Error: Could not load model tool/seo_url!

Does it has a solution? My OC version is 1.2.9

ah yea.. SEO was added afterwards I guess. Any plans on upgrading your cart?

I really would like to upgrade it but I don't know how and I am affraid I lost the template changes and the other change you did for me, remember? so if it can be done without losing anyting I would liek to do it, if you offer me this service tell my and how much is it to do it.

Thanks,
