Recently switched from v10 Enterprise Online to Enterprise self hosted on Ubuntu 16.04 server. Whenever we load our site, and go to a product page, the page gives us a blank white page with "500: Internal Server Error" and the top menu bar changes to just the Home and Back buttons. This only happens when you are not logged in. The entire site works properly, except for on an individual product's page. Have tried reinstalling Odoo and werkzeug on various versions. This happens on other computer on our network, as well as on the server itself.

There is no error code on the page to give any help either. The server log does not show any information about loading the page or any issues encountered.
