I’m not sure why the Update Linkroll breaks WordPress, but it does. Also, the cron job I setup to GET links-update-xml.php doesn’t seem to be working once again, and I’m not sure why it broke, too. I don’t know what permissions to set it to. I’m sick of it for now, and I think until I upgrade WordPress to 1.5-beta, I’ll leave those two things disabled. I don’t feel like messing with things at the moment.
