Can't open new single section I created a new Single section and named it "test", added some content and tried to view it on domain.com/test. Unfortunately I get my default server 404 and not the new single section.

I tried to add a new route using "test" =&gt; "_layout" but can't see any change.

Do you have any idea why this isn't working?

EDIT:

Here the both screenshots.

I hope that helps.
You will need to add a template called test.html that extends the "_layout.html" template. The layout template is just a wrapper template, and with the "_" in front of it, it will always be invisible to a browser.

Take a look at the twig references on extending templates. Also look at the templates supplied with the initial install to get a better idea how this works.

Twig Extend

Routes are for more refined routing of templates and you should not need a route for current implementation.

Imagine if "_layout.html" were named "_wrapper.html" and it makes a little more sense.
