Hi guys,
Just to let you know, I (with a little help!!) figured out what was happening here.
My temp directory on the server wasn't allowing the txt file to be copied, therefore wasn't finding any file to import.
This was because of my zencart being hosted on a Windows server, and of course I should have, as per the install.txt file, followed the instructions to get the permissions on that directory changed:
"** your temp folder must have owner permissions to read/write/execute (chmod 700) for EP to work.
EP now adjusts this for you (unless you have a windows server - ask your host to adjust permissions on this folder for the IIS web server)"
Note to self: RTF i.txt!!
Rgds,
J.
