I created a doc page about how developers can configure Concrete to use redis.

As [reported here](https://github.com/concretecms/concretecms/pull/7206#issuecomment-1594625098), I couldn’t choose the right section where that page can be published (I couldn’t find the “developers” section, only “[archive] Developers Guide”).

Today I tried again to edit that page to check if I could move that page to the correct documentation section, but I see this error on the page:

Hi @mlocati - we will take a look at this and post back.

All right, I have moved that to the Tutorials section here so that should be accessible there so that’s good: [Using a Redis Server :: Concrete CMS](https://documentation.concretecms.org/tutorials/using-redis-server-tutorial)
