1. I went from eCart 4 to 6, never installed 5 so that can't be it.
2. OK. I still have CC (13.2) installed and working from there, so no worries. But I still get JS messages with that. I will remove the config folder and do fresh installs of the .zxp files...
UPDATE: Please see attached screenshot. I dumped the config folders and started over with the .zxp files. This is CC (13.2), *not* CC 2014.1. It appears the error is due to the fact the js file is not there...
