Getting "Uncaught ReferenceError: acf is not defined" error on ClassicPress

[zcraber]

Tried installing SCF 6.7.1 on a fresh ClassicPress 2.6.0 installation and it's giving Uncaught ReferenceError: acf is not defined error in console.

This error is causing several issues in field and post creation/editing. Downgrading SCF to version 6.4.2 resolves it.
