I'm at a bit of a loss for how to troubleshoot this one.
The problem Library/Hope/Multi1/04-01-Linear-transformations/Lin_trans_11.pg works for everyone except one student. When Webwork tries to render the problem page for him. It errors out with the following:
'require' trapped by operation mask at /usr/lib64/perl5/vendor_perl/Encode.pm line 5. Compilation failed in require at /usr/lib64/perl5/vendor_perl/Encode/Alias.pm line 22.
The following information can help locate the source of the problem.
