I've had several students who report that the plots in my webwork assignments are not loading. I am attaching a screen shot so you can see what's happening. Here are the URLs for some of these problems:
I have advised students to use the latest version of Chrome or Firefox as their browser. Two of the students experiencing this problem reported that they are using Windows 10. I am using webwork on a MacBook Air using firefox, and the graphics load fine for me.
Thanks in advance for any ideas you may have for fixing this problem.
