I tried to search the forum for this first. The pages link on the Grav Documentation (Learn) site generates a server error. Here is the link: https://learn.getgrav.org/17/content/content-pages.
Here is the text of the error:
Sorry, something went terribly wrong!
0 - Unexpected end of template in “@Page:/home/grav/webapps/learn/user/pages/02.content/01.content-pages” at line 195.
This issue only seems to affect this one link. The rest of the site seems to be working fine.
