** Using WeBWorK **

When I go the Instructor Tools page and try to sort a class list by section and display only those students in a particular section, the display window comes up empty.

The second problem concerns the Show Past Answers feature. Any attempt to use this feature generates the following error:

Can't open the access log /opt/webwork2/courses/M144Pollina/logs/answer_log

I've tried adjusting the permissions, but to no avail.

Has any one encountered either of these issues? Any help would be appreciated.

Make sure that the webserver has execute access for all directories enclosing the directory /opt/webwork2/courses/M144Pollina/logs. and that it has write access for this directory.

It's possible that the webserver does not automatically create the answer_log file. You can workaround this by typing

echo "" >answer_log

in the directory /opt/webwork2/courses/M144Pollina/logs

Make sure that the file /opt/webwork2/courses/M144Pollina/logs/answer_log

can be written to by the webserver.

Hope this helps. Let us know if you isolate the problem.

Thanks. I'll give it a try.

I figured out the first problem. I used a time (8:30) to designate a section. Once I removed the colon, everything worked fine.
