RSS Feed Problems

Something weird is going on. I have a FeedBurner account and
the one feed from this site works, it defiantly works I’ve tested it and it
works OK. Now this feed is not showing any stats on FeedBurner? Yet awstats
says there has been loads of traffic so what’s going on?

ijoomla-rss feed has been released, now this worked
perfectly prior to my upgrade of Joomla
to 1.5 now I admit the release is beta but surely it should work of sorts?

Anyway stupid FeedBurner says;

The URL you entered does not appear to be a valid feed. We
encountered the following problem: Unknown feed format encountered (The root
element is [Element: <html [Namespace:]/>])

And also;

Source: <!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “”>
<html xmlns=”” xml:lang=”en-gb” lang=”en-gb” >

Its all double Dutch to me.
