Thanks for your explanations. Iam not publishing through ftp. I just logon to see if the folder is there, and it is there.

I have just tried publishing as you said but it won't work. I went back to cpanel, delated the domain name & recreated it again. republish the site, but this is the messege i get:

"Error 550 can't change directory to public_html/subdomain.domainname.com no such file or directory"
