Thank you, Chad. I have a clearer understanding now on how to proceed. Time and coding skills are not on my side. (I am a newbie.) So these directions will serve me well. I had run the Auto Install script for ZC 1.5.1 on my web-host and then manually updated to ZC 1.5.3. Do I delete all the files in my store folder and then start over? Or is there a ZC auto install script for ZC 1.5.3 that I can run that will overwrite the current installation?
