Dear @Richard-K
I'm sorry it took me so long to reply to you.
I found out that the blog is not working.
What I was doing was adding the page as a blog in the "projects" section of the admin panel.
Some people have told me that the order of publication is linked to changing the descending order of the "date" on the screen where the list of projects is displayed.
[date]▲→ [date]▼
It was automatically lined up in the order it was published, not the way it was lined up using gridders.
If it is difficult to change the order of publication, I will try to figure out another way to publish.
Thanks again.
