I'm new to Webwork, and am the network administrator supporting some of our faculty who desire to use the program.
We are having an issue that manifests itself when a student attempts to download hardcopy for a homework set. At the Hardcopy Generator screen, the only option I have is to generate a PDF copy. When I click on the "Generate Hardcopy" button, I get this error:
An error occured while processing your request. For help, please send mail to this site's webmaster (email@example.com), including all of the following information as well as what what you were doing when the error occured.

Any ideas on how to proceed? This is running on Apache 2.2.6 on a Solaris 10 server. I'm using all of the normal paths for a standard Webwork 2.4 setup (/opt/webwork). I don't have any problems viewing problems elsewhere. The only thing that is (apparently) slightly unusual about my setup is that the Mysql database server hosting the db's for this instance of Webwork is on a a separate server, but I have modified the database connect string, and haven't had any problems elsewhere--at least none that I have yet to discover.
Thanks for any light your pointers you could send my way.
