When trying to lock/unlock a page via the page sidebar Image 1, a user is only able to lock it. When they try to unlock it, they see the error Image 2, and the page cannot be unlocked.
However, they can lock/unlock the page successfully when trying via the site admin console 3.
The error 1 when unsuccessfully trying to unlock a page appears because the page doesn’t include the
cq.shared client lib.
To fix this, the user needs to put a dependency on the clientlibs mentioned above to have it loaded for their custom content page.
