RSS Feed Duplicate Post

[varsityhero]

The RSS feed for my CMS content is releasing duplicate posts to Ping.FM. I asked for help from Ping.FM and they told me the <guid> element must be unique and not change. In my RSS feed it changes everytime. How do I fix this? I'm running the latest version of vB... 4.0.3 Patch 1.

Anyone?

I am having a similar issue. My RSS Feed for VBulletin 4.1.8 is pulling Feeds fine. However, every 12 hours, if there are no new stories from the RSS Feed the feed pulls the same story as 12 hours before and posts it again effectively making a duplicate post.

Is there a way to only have the feed manager pull the same story only once & ignore any duplicates?
