Interesting facts... I just rebooted the server (I'm always worried when rebooting a remote server that it won't come up again), and no change... However, it is interesting to note that this is the first time I ever rebooted this server in a year and a half

Anyway, I also fixed a local DNS resolution issue on the server (added some more dns resolvers) but no change. Perhaps a database issue, though I have never seen the wiki have any issues - especially a blank screen, so I'm not really sure where to look. None of the config files for it have been touched in a year or so. I'll try upgrading to a recent version and maybe that will kickstart it back up.
