I'm running the latest EP Lite/Participad/WP and they all run fine independently, but once you enable the Participad plugin with EP lite running WP just hangs indefinitely. No errors are shown, but the PHP process runs at 100% for the entirety of the page load. I'd love to be able to get you something to be able to replicate it but it's a brand new bog standard set up - WordPress Multisite 3.5.1, BuddyPress + Participad. Do you have any ideas where I could check what's going on? EP, nginx and php-fpm don't show anything in their logs regarding a problem.
