I had this problem also and found another possible reason.I was using
the long URL to access
Workspace:http:///lc/libs/livecycle/core/content/login.html?ap=1I
get the error about the cookies in every browser (Chrome, FF, IE and
Edge), both on the server itself, and through remote access.When I
switched to the short URL, it works:http:///lc/ws So
this error seems to have multiple causes, which reflects the previous
comment that it appears to be a catch all, when an unexpected error
occurs.
