Sandy,
That is the strangest thing as it appears that your FCKeditor instance is trying to use the ColdFusion connector that is bundled with a native FCKeditor installation.
What is weird, though, is that if you are using the latest HTMLEditor, I don't think WebAssist even kept the CFM connector files in the version that gets distributed by the extension.
By chance, did you have an old iRite installation on the same page and perhaps an unneeded include is being called?
Best regards,
Brian
