Xenforo notices posting across boards?



I have a strange thing occurring. I have a "Live" install of Xenforo (in the servers "root" folder), and a "test" server installed in a different "test-development" directory on the same physical server.

I have verified that both of these installations are using entirely different databases, so that's definitely not the problem.

However, I posted a "notice" message to the LIVE server today, and when I go to the test server, that notice is appearing there also.

Is this some kind of cache issue - or is there some other kind of misconfigration I should be looking for?
