I've been running UnRaid for a few years now, and today for some reason when I logged in the web GUI was only displaying text. I have tried rebooting several times, and I put a fresh install on my boot USB with the USB Creation Tool. I'm having trouble finding other that have had this problem, so I am not quite sure what the underlying issue is or how to fix it.
<Update> The GUI seems to work fine on my phone for some reason, so it appears to be just an issue with my current computer.
<Update> Works fine in Firefox aswell. After some digging around Google did some stuff about blocking unsafe URL's, and when I retyped in the default UnRaid dashboard URL (and not my old bookmarked link), it worked fine.
