I will do it !
Thank you for your answer.
It’s done.
The request number is #27006.
Hi all,
I encountered the same issue on my website. I switched to twenty twenty-one theme and deactivated all the plugins excepted the maintenance one (my site is online), without any difference.
The first page appears in the admin menu lateral bar. The second and following can be created and edited, but are not visible. Parameters, as parent, for example, can be edited but are not taken into account.
Curiously, those pages appear in the “Admin Menu Editor” plugin setting screen, but as hidden (with a crossed out eye icon).
I hope that will help.
