I want to approve, but I don't see a test. So it makes me nervous. Would this be hard to test to make sure we don't break it in the future?

[SanderElias]

It needs quite some setup to do the test. Also, it is mostly covered by existing tests.
It is a bit of a chore to set up an extra test for this, as we need to add an extra blog folder where the name of the folder isn't the same as the route for the blog. in addition to what we have.

Did push an update. Moved the blog files into a different folder, and this makes sure the test are ran for this change. The current tests will work just fine for this change now. No additional tests are needed @aaronfrost
