Over the weekend we were hacked into, and all of mat295 was
deleted except for the directories.
Anyway I have a system up now with demoCourse working fine.
I've tried to restore mat295 from backups in two ways.
1. I copied the entire mat295 backup directory structure and
then ran the course setup script. Everything I've tested works,
except that when a problem is typeset I get
Error: /usr/local/webwork/system/cgi/cgi-scripts/processProblem8.pl: createDirectory error
Can't do chown(-1,502,/usr/local/webwork/system/courses/mat295/html/tmp/l2h/11-83525/)
and indeed the directory 11-83525 is owned by www-data.www-data and
the ownership cannot be changed to andrew.MAT295. I've tried several
things here none have worked.
2. I created a new course mat295a ran course setup etc, then
copied in all the mat295 directory structure, same problem occurs.
Perhaps most perplexing is that if I try to typeset the
problem a second time it works.
I'm about ready to declare defeat on using the backups.
