When i try to modify a post article with the default WordPress editor, the page switch automaticaly to the Toolset template editor.
And when a want to see the publish article thier is nothing displayed except for the Title and features image.
Is is because you have our Layouts plugin installed and there is an empty Layout assigned to the post type. This is why your page is not showing up with any content on it.
If you're not using this Layout I would recommend that you delete it. If you are using the Layouts plugin to build your page's templates then you will need to add the Content Layout block to your layout.
This will allow you to edit the post itself without redirecting you to the layout page.
Can you tell me how and where (step by step) can I delete the layout ?
I tried to delete the layout by clicking on the bin but it's not working (see the screenshot)
I tried both 2 methods you suggested to delete the layout, but it's does not work.
The link for trach is strikethrough (see the screenshot).
It say that the layout is assigned to some article.
I can send you the access if you want to have the context.
