I tried to add them the same way the above poster tried (just not as author), i tried adding them to the .htaccess file like this
RewriteRule feed/(feed|rdf|rss|rss2|atom)/?$ index.php?&feed=$1 [L]
but they just completely make wordpress stop working, not a single page works if added to htaccess. I am out of ideas. lol.
Thanks in advance.
