I set the plugin to use permalink as the structure /sample-page (etc.) and once I clicked save I went in, changed one of the page permalink names, refreshed and no pages on the site can be found. Deleted my cache and cookies, still no dice.
I have a dedicated server, the uptime is phenomenal so it would be one major coincidence if it was just ill-timed downtime. Any ideas? I can't even get to the admin login area.
