The offending line of code is attempting to create the fckeditor component. This tells me that the fckeditor portion cannot be found. This is the fckeditor.cfc file that is in the WA_iRite folder. You must ensure this is present on the server. You must also ensure that you have the fckutils.cfm page on the server in this location as well.
If you can ensure that the files are on the server in the correct location then there may be a mapping issue on your CF server for the fckeditor value.
I have been informed that the newer CF Servers may have fckeditor built in by default, this could interfere with this setting. If you can confirm that you have uploaded the other files needed in the iRite folder for this then it is likely a mapping issue that you are experiencing. If you do not control the server you should ask the host about any fckeditor mappings that exist on the server.
