My installation seems ok (templates return 'consolation prize setting with a valid post' but there are no posts showing with even the lowest settings, it's clear there is no cache. I'm on 3.1.9. I've deactivated, reinstalled and there's always an error message
"The plugin generated 202 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin."
Should I try the new beta?
