Can't change any node permissions

[TheLaw]

I enountered a problem where I could not modify any node permissions after moving to a new server. Turned off all add-ons, defaulted the forum to the default theme and received the following error:

Oops! We ran into some problems.
Oops! We ran into some problems. Please try again later. More error details may be in the browser console.

So I looked in the browser console. I've never encountered this issue before and I'm surprised that this would appear as well.
