Rooted. Thanks @felamos. Learned something about w**m
From what I can tell so far the YAML parser is at least meant to work. Anyone else getting a blank page with ‘Due to security reason this feature has been temporarily on hold. We will soon fix the issue!’ everytime they post something to the Yaml servlet?
Getting this message is normal when you send something that doesn’t do what’s needed - except for when you send garbage and you get the trace that other people mentioned.
For root: getting an error when running the w**m-related command can also be normal and doesn’t necessarily mean some other user bricked the machine, just read through what you have.
Friendly reminder to clean up your room before leaving the box.
