Hi,
Looks like the static content (stylesheets, javascript and images) isn't loading. Check the paths in settings.py point to the correct installation directory. Depending on whether you're running with DEBUG setting set to True or False, there are different ways to providing the static content. This is all Django stuff, so the Django documentation could help out too.
Btw. peach itself does not contain an autograder. The autograding backend we use locally hasn't been released as open source (yet).
