Describe your question/issue in detail
From today I cannot create new articles.
I am using the new " Upgraded and faster page list" update (Upgraded and faster page list),
Yesterday, using the same new UI, it worked fine but today the UI do not let me choose the type of page I want to create. The pages type are repeatable but I cannot select any of them and the tooltip indicate they are singleton.
Impacted feature
Page creation ("Create a new page" button)
