Our IT department hired an external consultant to install us a new WeBWorK version and now, we cannot generate PDF. We can generate Tex but I would like the PDF functionality. And since I have to help our IT department fix this, any detailed help would be appreciated ;)

Here is the error message :

4 errors occured while generating hardcopy:

- Failed to convert TeX to PDF with command '
`cd /opt/webwork/webwork2/htdocs/tmp/Linear_Algebra_I/hardcopy/work.ASIImIbU && /bin/pdflatex --shell-escape >pdflatex.stdout 2>pdflatex.stderr hardcopy`

' (exit=1 signal=0 core=0). - First error in TeX log is:

WeBWorK was unable to generate a paper copy of this homework set. Please inform your instructor.

Thank you.
