We're on Magento 1.9.1.0 Community Edition. While resolving issues on our Google Merchant Center account I ran across the following issue. When i access a product through the “direct” url (http://www.sycamorelifesciences.com/celltreat-25-ml-serological-pipette-sterile-bulk-packaging-case-...) and I inspect page source, I do not have a 404 error. When i access a product through the hierarchical url (http://www.sycamorelifesciences.com/products/consumables/serological-pipettes/celltreat-25-ml-serolo...) and I inspect page source, I have a 404 error for the following url: http://www.sycamorelifesciences.com/products/consumables/serological-pipettes/. Does anyone know where this URL is coming from and how I might go about resolving it?
