I realize those versions are extremely old, but the last day or so I have been working with Wicked Edge‘s Web admin with fixing the RSS feed from their site. Mail and Outlook both saw everything fine, but the W3C RSS validator knew it was broken, and Google Reader would produce very odd results, mainly by reading the content, but the URLs would be incorrect.
The issue boiled down to Joomla 1.5.20 not encoding ampersands in the RSS section. So instead of:
http://www.wickededgeusa.com/index.php?option=com_kunena&func=view&catid=3&id=5979&Itemid=63
You’d get (note the missing &’s):

I am not a knife nut. But, I do like nice things. My kitchen knives are KAI Shun’s, and they’re very nice, and pretty expensive to boot. And after 5 years of use, they finally needed sharpening. Unfortunately, from the time I bought them until now, Kershaw no longer offers free sharpening for life. They have instead outsourced the sharpening to a company called Perfect Edge in the Bay Area of California. So, I bit the bullet, and sent off my entire knife set via FedEx, and waited. About 5 days later (3 business days I think), I got a call they were done, and that the charge was about $40 with shipping back. Part of the reason it was that high was they had to “restore” a knife because the tip had chipped off ages ago. Fine. So, I pay them, and they ship them back.
