We have several RSS Feeds set up and one is failing.
DotNetNuke 4.9.1
Publish 05.03.01
The five displays are set up as Custom List, Article, Category. They only differ in the category. Four of the displays are a subcategory of the one in the fifth category. The fifth category, the one that fails, is a top level category.
I was able to reproduce the error by putting a Publish module on another page and configuring it separately. If I specify the top level category, it fails. If I go back to page settings and specify another subsidiary category, it works. Fails and works refers to the RSS link. All that I need to do is change itemId to another category, and the rss feed works.
