Made FAQ available on frontend can't access them on backend

Hello i have used the code provided in this thread to make the FAQ's available to non logged in users.

https://premium.wpmudev.org/forums/topic/how-do-you-configure-the-simple-sitemaps-for-multisite-with-nginx

Once i did that i could no longer access FAQ's from the backend.

Atm i added the code back. But it would be awesome if someone can assist me with this, i would really love to have faq's available for non logged in users.
