### After updating, making hardcopies does not work

I upgraded webwork2 and pg and things seem to be working except I can't get webwork to give hardcopies.  When I select a problem set to make a hardcopy, the screen shows it's working at it -- as it usually does -- and then I get a "HTTP 404 Not Found" page.

Thanks --rac

Hi Robin,

Can you figure out what file it's looking for that it's not finding? For example, if you can look in the server's error_log file, it might say what the filename is that it's not finding and give a hint as to where the problem is.

It sounds to me as if the WeBWorK server may be failing to create the PDF correctly. If it's getting most of the way there, it may then be that the URL for the hardcopy gets sent to the browser but there's no file there, which would result in the error you're seeing. There may be information in the WeBWorK log, or it may be by changing the variable \$WeBWorK::ContentGenerator::Hardcopy::PreserveTempFiles in webwork/lib/WeBWorK to 1 will let you see what file(s) are causing problems.
