index.cgi and its parent directory are mode 755 owned by the same owner, the DocumentRoot of the site below. The site-enabled/005-icons file has:
<VirtualHost *:80> ServerAdmin [email protected] ServerName iconlibrary.mobi ServerAlias www.iconlibrary.mobi icon.stornge.com icons.stornge.com DocumentRoot /home/jonathan/ikon <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/jonathan/ikon> Options ExecCGI Indexes FollowSymLinks MultiViews AllowOverride All AddHandler cgi-script .cgi DirectoryIndex index.cgi index.html Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

I believe that /index.cgi may not be running as a side effect of something preventing /*.cgi from running. I tried to run the index script as /, then as /index.cgi, and then copied it to /icon.cgi which behaved identically to when it was invoked as / or /index.cgi.
Suggestions?
--EDIT--
I went through the level 1 technical support questions before posting: for tech support, "Is it plugged in? Is it turned on?" I've checked the logs and confirmed that the program runs as expected when executed from the command line, and also checked permissions, etc. I was really hoping for level 2 or level 3 kind of support, not "Check your logfiles; maybe you have a syntax error." I already stated in the original question that I checked the logfiles and nothing's there when it serves up a 500.
