I have two different iWeb sites: one is hosted elsewhere and one I'm trying to host (using a personal domain I've already configured for my mobile.me account). Here's the problem (I think...in my very limited MacWisdom):
I originally tried to host my first site on MobileMe but decided later to FTP to another server for hosting....now those files are still appearing on my iDisk....so when I try to publish my new site (completely different website) it appears both sites are mixed.....with two "Welcome.html" files....I think this is the reason it won't PUBLISH correctly. I can publish to Local File and it works beautifully.......
I believe that I need to delete the files from the first website but don't want to damage my site files that I'm using to make changes to that site (the one hosted elsewhere). I've tried to delete them in iDisk but this is not an option (won't delete). If anyone can talk me through this process I would be so pleased!

Only way go to iDisk/Web/Sites and drop the website's folder into the trash and empty trash. If that doesn't work (I see no reason for that to happen) I don't know.

If you trashed the folder and emptied it and still see the old website Empty your browser's cache.
Safari=>Empty cache
and reload the site.
