I am using Lion 7.4, there is not an option to change location to iCloud, only my name at me.com (mobiel me) which of course now is defunct. Any suggestions.
Open iCal>Preferences...>Accounts...then delete your me.com account, and add the iCloud account. Use the +/- symbols at the bottom left corner of the Accounts preferences window to add/delete the accounts.
I may have misunderstood your post...subscribed calendars are not displayed on iCloud.com.
