To provide a unified editing experience for Adobe Muse users, starting with Tuesday, Feb 2nd 2016, all Adobe Muse sites published to Business Catalyst will be editable through InBrowser Editing (https://inbrowserediting.adobe.com/) instead of BC's integrated InContext Editor.
As such, when clicking on Edit button on the upper ribbon, user will be redirected to InBrowser Editing to edit the site's content. Once done, user can return to the Business Catalyst admin interface without having to login again.
Regular Business Catalyst sites will not be impacted by the change.
