Error when try to add the rss feed of any subreddit to Commafed.

[HeyThursday]

Whenever I try to add a subreddit url address to Commafed I get this. "org.xml.sax.SAXParseException: DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl"

You need to add .rss to the url, as described here https://www.reddit.com/wiki/rss
