I notice that the supersearch script is erroring with a 500 or similar on the London site.

Could someone who has access, please take a peek at the server logs and find out what is happening.
If it's a perl scripting problem let me know, as it's my code :).
However, I doubt that this is the case, as the same script and version of the OpenGuides site is running elsewhere with no problems.
