We have an interesting problem with Webwork 1.9. When we have the diagnostics disabled, the part of Webwork that compiles and lists student scores on the problems won't run. It generates an error message along the lines of "Can't find diagnostics; fatal error".

When we enable the diagnostics, everything (including the compilation of student scores) works fine, but the error messages make a mess both of the pdf files and the problems as they appear on screen.

Currently, as the semester starts, we have disabled diagnostics so that students can easily read the problem sets. But this means that we professors can't see how the students are doing.

Can anyone suggest a fix or something that we should try?

Thanks, Tom

We've found that from the Professor's page,  the "View Statistics by Section" and
"View Statistics by Recitation" choices work fine, but that the choice
"View Students Progress in ...."  [set 0]   doesn't work.  Instead, we get the
error

Content-type: text/html

 

Software error

Can't locate object method "disable" via package "diagnostics" (perhaps you forgot to load "diagnostics"?) at /local/webwork/system/cgi/cgi-scripts/classlist.pl line 184.

 

Please inform the webwork meister.

In addition to the error message above the following warnings were detected:

We figured out a solution. 

By commenting out line 184,   #  disable diagnostics ...  we have the grading part working. 

I still would like to know whether others get this error too, or did we have something
set wrong in our Webwork setup.

It looks like you need to update your Perl library diagnostics.pm in /usr/lib/perl5/perlxxx/ to a newer version from the CPAN archives.
