Re: Cannot delete bookmarks
This is the same mistake once I made. In fact, after clicking on the x, the page is renewed in such a way that you think it's the former page but it isn't. This time, look at below the structure list table carefully and you'll see these 2 links:
Destroy the structure leaving the wiki pages
Destroy the structure and remove the pages
After you click on either of them, the request will be fulfilled!
