OK, if I had hair I would have pulled it out by now. For several months I've been getting this error from BlogCFC, but I can't track the true source to remove the offender:
Script Name: /rss.cfm?mode=full&mode2=cat&catid=9856ECF2-3048-71C2-17879EB46D54D46F Detail: An invalid XML character (Unicode: 0x19) was found in the element content of the document.
I can't find this character anywhere. No clues at all. But, it's playing havoc with some RSS readers, apparently, and loading my inbox. So, anybody have some suggestions how I might find this?
