Some users are experiencing issues with Apple's MobileMe when attempting to publish their iWeb sites to it. MobileMe makes publishing your websites from iWeb easy with one-click, Mac OS X integrated publishing.
Apple Support Discussions user "Durandel" reports the issue:
Error: Couldn't reach the MobileMe configuration server. Try publishing again later.Later in the thread "Durandel" offers a solution that worked for them:
Well, I tried later. 24 hours later. What's up?
- Go to Finder -> HomeFolder -> Library
- Move entire folder "Caches" to desktop
- Restart iWeb and publish
- It should work now
- You can now delete "Caches" folder in desktop.
