XF 2.1 Web console errors when trying to login/register

[TylerV]

I recently installed Xenforo and I'm having this issue when I try to login (by clicking login on the page).

When I check the web console I get this error: https://i.gyazo.com/3e852c1cf4309339f366bc803acac5a2.png

I can't figure out why this is happening, I appreciate any help. I have reinstalled twice and have made sure that I properly followed the guide to install.
