New Category Page Showing 404

Question

So I have made a new category and copied all settings from another working category with a new name and url etc but I get a 404 when hitting the category frontend.

When trying to debug this I have found the following...

#File: app/code/core/Mage/Catalog/controllers/CategoryController.php
if (!Mage::helper('catalog/category')->canShow($category)) {
    return false;
}

The CanShow function above returns false when I hit the category.

When looking at the below file you can see my comments regarding what is happening:

#File: app/code/core/Mage/Catalog/Helper/Category.php
public function canShow($category)
{
    if (is_int($category)) {
        $category = Mage::getModel('catalog/category')->load($category);
        //THIS $category VARIABLE IS NOT SET
    }

    if (!$category->getId()) {
        return false;
        //NOT RETURNED FASLE
    }

    if (!$category->getIsActive()) {
        return false;
        //NOT RETURNED FASLE
    }
    if (!$category->isInRootCategoryList()) {
        return false;
        //NOT RETURNED FASLE
    }

    return true;
    //RETURNS TRUE BUT NO $category IS SET
}

If I visit a product inside the category it works fine and the category URL is in the URL e.g. /shop/categoryname/product-url/

I have flushed the cache and reindexed etc.

Can anyone offer any advice on what I can do to stop this 404? Other categories created in the past are working fine, only new ones are affected!

Sometimes it is because of URL change. Change the URL Key and uncheck the "Rewrite old URL" option. Let me know if it works. Apart from that make sure that it is tagged under Root Category :)
