This looks like a permission problem having to do with creating images for equations -- nothing directly to do with the pop-up list.

Check that /opt/webwork/webwork2/tmp exists and that the webserver has write privileges in that directory.

Next make sure that the file preview.sty exists somewhere in your TeX macros hierarchy -- it's required by dvipng. You can run
pdflatex ....webwork2/bin/check_latex.tex to see if there are any errors or it can't find that file.
