That error is too vague, an ISE 500 can imply a lot of things. What is the actual error logged within your server's error logs?

Something like this should be logged in your Apache error log (usually in a specific logs directory or within the Apache install directory), but I'm unsure if your VHost configuration will place a specific log elsewhere.
