Not necessary for what we are talking about now, you are right. But I need it to redirect to my tomcat server when I have a “normal” visit, and keep it for the php/apache2 when it comes for the wordpress blog.
I tried for you what you point, but the result is the same even with the working new config.
But what about the 404 you made me see in the Github thread? Does it mean I should somehow get “wp-json”? How could I do if it’s the case?

I made lots of installation attempts and “installation” at the end is not much more than a download.
It is clearly a bug. I have exactly the same behavior in FF than here:

I tried to follow but not my configuration
No solution from WordPress so far

That’s the same document I read, followed and mentioned in this post. But thanks

I found this thread

They talk about a similar issue, and the conclusion is that one Theme is behaving oddly.

In my case it works too. After changing from “Tweenty nineteen” theme to “Tweenty sixteen” I could open “Add post”
