With D8, I have a node (content type: basic page) that I use as a custom 403 (access denied) page.
I set this as the custom 403 page on:
/admin/config/system/site-information. The path is
/node/21, and the alias is
On the block admin page, I added the user login block to the content region. I added the restriction "show only on certain pages":
I have a view that requires "add content type ABC permission" to access. The path to the view is
/view/abc. The anonymous user does NOT have this permission.
So, as an anonymous user, I go to
/view/abc and am shown the content of
/node/21. BUT, the user login block is not shown.
If I go to the block administration screen and remove the "show only on certain pages" restriction, then I see the block as the anonymous user on
/view/abc, but I don't want to show the login block on every single page; I only want to show it on the pages that are 403s.
What is the "path" to use for the user login block to only show it on a custom 403 page?
