iWeb Publishing Problem - HELP!

Hi - I am having a problem and have been reading page after page of support discussion to no avail. I have a site created on iWeb (Mac) and have published it to a folder. I’m now trying to bring it up on my site through Dreamhost. I am using CyberDuck and at times the WebFTP within DH. I’ve tried every way I can think of and each time I upload, when I go to the site to check it out, I have a screen that says this:

You don’t have permission to access /index.html on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I just cannot figure out what I’m doing wrong… I could really use your help! Thank you very much.
