What I CAN do is:
Export all of my web designer 9 files to my local drive then use FileZilla to FTP upload them to my Magix Online website
Works fine. website works fine. Life is groovy, apple-pie and chevrolet.
What I can NOT do is:
Use the "Publish" button feature in Web Designer 9 to publish/upload my files to MOW.
I am using the correct userid and password (the same userid/password pair that is being used successfully to do the FTP)
