I don't know how to describe the fix...as it just worked itself out. Don't know how that would have happened. Yes, prior to the error I had already uploaded the files and ran the upgrade script.
Then I went to the Classifieds Admin link and that's when I saw the error however, I could still manipulate the settings in the Admin panel. I changed some of the new options and viewed the Classifieds....went back into the Admin link and the error was still there. I left for a couple hours and went back into the Admin link and the error was gone. I had refreshed a few times prior to my leaving as well.
