New page editor not working

[apay1-5603]

Bonjour !
After creating a new page I cannot edit it, the editor doesn't show the content. I attach a screen copy to show the default, not easy to explain with words ! In the attached image, the page is not empty, I've added a title and some text, then saved it.
Thanks for your help.
Antoine.

Is this a custom page type? does it work if you try to create a new 'Default' page type? Have you modified the YAML blueprints in any way?

Not a custom, it's default type page, and I didn't modify anything. I've installed GRAV on my Localhost to try it for a simple website and not use Joomla as I'm used to do.

I can't replicate this i'm afraid.. can you check your developer tools "console" to see if there are JS errors?
