Missing and mismatched blog posts

I noticed that some of the blog posts I wrote now give a permission denied error.

For example:

• https://live-tor-blog-8.pantheonsite.io/blog/ooni-bridge-reachability-study-and-hackfest (gives permission denied error)

• https://live-tor-blog-8.pantheonsite.io/blog/tor-project-hiring-developer-ooni (redirects to /blog/tor-misused-criminals), but then shows the correct article with a different author. I also don't see this appear in my list of posts: https://live-tor-blog-8.pantheonsite.io/users/art
