I wonder why you should do that but I maybe there is a reason..
All I can think of ("quick n dirty solution") would be to empty the
session table. I'm not familiar with Ion_Auth - maybe you have
to empty a related table where the logins are tracked (like the
CI session table). On the next page load the user should be logged
out. Didn't test it but should work.
