Thread:Extension talk:RSS/RSS does not accept results of Semantic Mediawiki query (2)

Hello,

I've saved the RSS feed as a semantic property (using Semantic Mediawiki); I then want to use RSS extension to output result of this RSS feed, which is retrieved by semantic query:

However, the feed does not show, only the following: Extension:RSS -- Error: Not a valid URL: http://www.feedyes.com/feed.php?f=1KngF5PQxE5QSQ7K

However http://www.feedyes.com/feed.php?f=1KngF5PQxE5QSQ7K works fine.

Please advise.
