|Ok, I didn't read things carefully enough.
Another possibility is that this is a problem with latex2html cached
images. "Delete Problem Set" deletes all cached images, but maybe if
this wasn't run (which contradicts what is implied by the above
message) or if permissions were such that this failed (which would be
very unusual), then maybe some bad cached images of the screenHeader
verbiage are present.
This would cause a problem (assuming $htmlModeDefault= 'Latex2HTML';) when trying to view the list of problems.
Try two things. The easist would be to go to where the cached images are kept and remove all screenHeader files
rm -r (tmpDirectory)/l2h/set4/screenHeader-*
(be very careful). The other thing would be to edit your webworkCourse.ph file temporarily changing
$htmlModeDefault= 'Latex2HTML'; to
If the latter works, the solution is to do the former and change webworkCourse.ph back to the original setting.
