500 Internal Server Error accessing thread
 

On my new vb5 (beta 26) install I started a thread, a couple of replies we exchanged and now the server returns a 500 internal server error when trying to access the page.

http://new.ragga-jungle.com/forum/mo...-be-done-still

The thread is in a forum that would normally be hidden from the public, but I have changed the permissions so that unregistered users can see it now. If you try other pages on the site they work just fine.

The server error logs don't reveal any information:

Code:
[Sun Jan 27 20:34:59 2013] [error] mod_fcgid: process /home/ragga-jungle/domains/new.ragga-jungle.com/fcgi-bin/php5.fcgi(18599) exit(communication error), get unexpected signal 11
[Sun Jan 27 20:34:53 2013] [warn] [client 206.248.190.190] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://new.ragga-jungle.com/

I also tried setting up all of the different log files in the "Error Handling & Logging" section of the options, but none of the log files are being created.

Any help on next steps for debugging this?
