"Service unavailable" message
I'm having a problem with multiple-choice question types. The pages are slow to load and several of the ten multiple-choice messages on the page refuse to load and instead show an error message, as follows:
===========================================================================
Service UnavailableThe server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.
