This message only seems to occur from the admin interface. admin_sessions table is empty and checks out OK so that doesn't seem to be the problem. It only occurred after I did the last update. Tried on two different browsers. Any thoughts?
The words appear in orange underneath the control panel login.
In Chrome, the problem is different: I get “The requested page could not be found.”
I'm sorry, I should have gone in and updated. I opened a ticket. The problem appeared to be cache related though it happened on ALL my browsers. I emptied the sessions tables and about an hour after that it magically disappeared.
