template/not-found

A Template that a Route renders, or that another Template extends, includes or imports, is not in templates/. Each Route has one default Template, such as posts/entry.html for an Entry of posts, unless Site config names another with template.

Example

[collections.posts]
route = "/blog/{slug}/"
(with no templates/posts/entry.html)

Fix

Create the file the message names, or set template to a Template that exists. Templates name each other by their path from templates/.
