Long slugs going to 404

[mrmathewc]

Issue description

I'm creating blog posts using collections and have added one of the posts that I have hosted on my WordPres website. I noticed that when the slug length was long, the route to the post doesn't respond and instead goes to a 404, however when I create a post with a relatively small slug, it loads the route/page fine.

Steps to reproduce the issue

1. Create 'Blog' as collection
2. Set route to: route: '{parent_uri}/{slug}'
3. Create long blog post with auto-generated slug called: "Big massive title to see if the routing works on the site"
4. Create small blog post with auto-generated slug called: "Test blog"
5. Try and preview both posts, 1 works whereas the other does not (for me, anyway)

What's the expected result?

Expected result is long-slugs should display the route the same as smaller slugs.

What's the actual result?

Longer slugs don't route to template or page and instead show a 404 page.
