Description

Fixed an issue where Autosave failed with a generic error message "Offline, can´t save." When the site was configured with ExternalApplicationOptions.OptimizeForDelivery set to true and with only a Primary host configured for the website in Admin > Config > Manage Websites.

As a workaround, you could disable ExternalApplicationOptions.OptimizeForDelivery or add a wildcard {*} host and an Edit host for the site also.
