How to remove remove .html at the end of a web page (CMS Modx)?

Question

MODX

Created a site for learning how to work with Modx: www.onhoric.hol.es
Cannot change the link in the Blog menu item to www.onhoric.hol.es/blog
Changed the .htaccess file as suggested on the toaster

RewriteEngine on
RewriteBase /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^.]+)\.html\ HTTP
RewriteRule ^([^.]+)\.html$ http://www.onhoric.hol.es/$1 [R=301,L]
RewriteCond %{REQUEST_URI} !(\.[^./]+)$
RewriteCond %{REQUEST_fileNAME} !-d
RewriteCond %{REQUEST_fileNAME} !-f
RewriteRule (.*) /$1.html [L]

The link stopped opening and began to give an error.
Tell me how to make human links. I've been wrestling with this all day.
