Visdom display abnormally: blank blue screen or messy layout.

Bug Description I am using visdom in a remote headless machine, and I use port forwarding to visit visdom. I map my local machine’s 8098 port to the remote’s 8097. I’ve done this several times and it works well. However, I rent a new machine and reinstall visdom recently, and visdom cease to function. Visdom cannot display nomally.

Reproduction Steps Enter steps to reproduce the behavior:

1. Install visdom in the remote machine(Ubuntu 18.04), map 8097 to the remote’s 8098
2. Config SSH port forwarding
3. Visit localhost:8098

Screenshots When I visit http://localhost:8098/, the display is as follows: As we can see, the layout is quite messy. Even I try to display some text through visdom.text, nothing appears. and if I visit http://127.0.0.1:8098/, I get a blue blank screen like this:

Server logs: For any issues, please include the server logs. These are printed directly to stdout on the machine running visdom (python -m visdom.server).

Also, in the first case(localhost:8098), the browser gives a “File failed to load: /extensions/MathZoom.js” message.
