Bugfix for viewing blog posts

What does this MR do?

Fixes a bug from !2001 (merged) that caused blog posts to not be visible.

Note: I moved the entry in the changelog because I think we didn't release !2001 (merged) yet. The bug is not on production.

How confident are you it won't break things if deployed?

Very

How to test
