Problem

When creating a RSS feed using RSS Feed Builder the code generated doesn't work with the RSS macro. It returns a message informing Page not permitted even if the user indeed have permissions to see the content. See screen shot attached.

Fix

There is none yet.

Workaround

Adding the username and password to the feed URL, as described in this documentation makes it work, but the username and password are shown in text plain, which created a security concern and can make this workaround unfeasible.
