By default, the ability to switch to the classic UI via the admin consoles has been disabled. Therefore the pop-up icons that was seen when mousing over certain console icons, allowing access to classic UI, are no longer displayed.
Every console that has a Classic UI version in /libs/cq/core/content/nav
can be re-enabled individually so that the Classic UI option once again pops up over the console icon when it is moused over.
In this example, we are re-enabling the Classic UI for the Sites console.
Using CRXDE Lite, find the node corresponding the admin console for which you want to re-enable Classic UI. They are found under:
/libs/cq/core/content/nav
For example
http://localhost:4502/crx/de/index.jsp#/libs/cq/core/content/nav
Select the node corresponding to the console for which you want to re-enable Classic UI. For our example, we will re-enable classic UI for the Sites console.
/libs/cq/core/content/nav/sites
Create an overlay using the Overlay Node option; for example:
/apps/cq/core/content/nav/sites
/apps/
Add the following boolean property to the overlaid node:
enableDesktopOnly = {Boolean}true
The Classic UI option is again available as a popover option in the admin console.
Repeat these steps for every console for which you wish to re-enable access to the Classic UI version.
