Single post in Quality of Life changes [UserScript]

I've been using the QoL stuff enabled in the site's options when I'm on my laptop, and it started glitching when I refreshed the shelter, so I turned it off and cleared my cache. But when I tried to turn it on again, it wouldn't work. I've tried logging out, clearing my cache, and restarting Chrome, but nothing works. The QoL settings thing isn't even showing up in the bar at the top of the screen anymore. Meanwhile, the QoL stuff works just fine on my phone. Does anyone know how to fix this?
