I really don't understand some things about htaccess. Reading, the advice is: never permit htaccess to users. So, can I enable htaccess but only for personalize something like this?
ErrorDocument 400 /errors/badrequest.html
ErrorDocument 401 /errors/authreqd.html
ErrorDocument 403 /errors/forbid.html
ErrorDocument 404 /errors/notfound.html
ErrorDocument 500 /errors/serverr.html
and obviously deny all other directives? so an user with own htaccess file, can only personalize that directives.
