From a "Wiki Page Library", I click the cog on the top-right, then click "Add a Page". Normally, I am prompted to name the new page and all is good.
As of today, I get a "Name your Page" prompt which adds a page to SitePages.
So, I no longer have any way of adding a page to any of my Wiki Page Libraries.
Does anyone know what I have done to break this?
TIA
