Keep getting JS error

I jeep getting this error
[13.06.2017 19:45:16] JS error: [ : xxxx] Uncaught TypeError: Cannot set property 'checked' of null

I’ve restarted my server, apt-get update/upgrade/dist-upgrade, cleared browser cache, yet I’m still getting this error. I’m not sure if it effects anything but it’s really annoying me. Anyway to fix it?

What browser are you using? I had a similar error when using Chrome. It turned out it was conflicting with an extension I had installed.

Try clearing cache and hard refreshing the page.
