Thanks for trying but I'm afraid it's still not working. I removed DE in extension manager, then downloaded ver 1.2.1 and installed it. Re-started DW and still getting an error on the import attempt: "Reference Error: site Domain is not defined."
Ray correct that. I was going to move on and work on some files in DW and suddenly the DE install opened up. After I let that run its course, I re-started DW and the site import DOES seem to be working fine now. Sorry for the initially discouraging news and many thanks for your perseverance with me on solving this. Good job!
