This error is error of permissions, which display products on home page. So follow below steps.
After patched, add some section in your admin.
Open System -> permission -> blocks
Here, You must add the home page blocks for allowed permissions. Like, if you want to display new products, so add New Block "catalog/product_new" in Block Name and "Is Allowed" is Yes.
After Add New Block, flush cache and reload home page. Now, New Products are displaying on HomePage
