The problem
Library/Rochester/setLinearAlgebra11Eigenvalues/ur_la_11_30.pg
seems to be working fine, but when I view an entire homework set in the Homework Sets Editor, and I click "Render all", then this particular problem causes the error "/webwork2/instructorXMLHandler: Forbidden" and does not render.
I checked and the file instructorXMLHandler is not located in /webwork2/, it seems to be located in /webwork2/lib/WeBWorK/ContentGenerator/.
It's not a big issue, since the problem seems to work just fine when rendered in the normal way. But I wonder if this points to a bug that needs fixing?

Maybe this is related to the problem I described in the following thread:

Yes, it looks to be the same problem.
