Hi Louie,
Your statement is analagous to "I was driving my car and it stopped. What is
wrong?" You can't tell precisely because I've given you nothing to go on.
You give us no details to work with. Were you in the middle of a session or
logging in? What were you doing when this happened? What software was
running? Has it happened before? Did you recently make any changes? Update
or install any software?
I can speculate as to causes, but without details I'd just be guessing.
Offhand I'd say something interrupted the Themes service, but what that is
and how you prevent it from happening again is anybody's guess.
