WebUI constantly crashes

So I have no way to currently use the WebUI as it crashes after about 5 seconds of loading the UI (doesn’t even load all the way). I’m not sure what the problem is, I recently restarted the computer the WebUI operates from, and also I was in the process of switching the Minecraft servers over to spigot version 1.11.2 .

It’ll load to this: https://i.gyazo.com/9b0024a0704409b2b92085358790b550.png
and then the page freezes and then waits about a minute and crashes.

Does /var/log/mineos.log show anything?
