There is a reasonable chance there might be some WordPress people on here - any debugging advice when a plugin's options page white-screens & wp_debug: true etc don't give any results?
@rocketpilot Good ol' `tail -f /var/log/apache2/error.log` not turning up anything?
(Apologies, I felt like chiming in but I've only barely used Wordpress specifically. Also now I'm realizing your toot was hours and hours ago so you've surely moved on. But it's the thought that counts?)
