I am running Mage 1.7 and want to replace an old product category with a new one. I have deleted the old product category and configured the new one. It is showing up correctly in my back end but is not rendering on my site. There is a blank section on the nav bar and the sub category says "Default Category".
I've made sure the category is active. I've set it up a few times and lastely I've cleared the cache and reindexed the site with no luck!
Are you sure that the category has been associated with the root category of your store?
In addition to that, have you set the "Include in Navigation Menu" property to "Yes"?
Make sure new category have any product assign ?
If no that assign and check with heard refresh.
