Just FYI, on this page of your documentation, there are two bad links (which lead to 404 pages):
The incorrect links are:
https://theme.co/docs/set-up-one-page-navigation
https://theme.co/docs/set-up-portfolios
To fix the links, replace set-up
with setup
.
Also, on the Wordpress dashboard, this link to the latest v5 release notes also leads to “page not found”. I don’t know what the correct one is.
