  I found a solution! I had my local environment setup with homebrew following [this article's instructions](https://echo.co/blog/os-x-1010-yosemite-local-development-environment-apache-php-and-mysql-homebrew). After looking at the php error logs, I uncommented `always_populate_raw_post_data = -1` in the php.ini file found in /usr/local/etc/php/5.6.
  
  I then restarted the brew services with `brew services restart php56` (install brew services by tapping gapple/services with `brew tap gapple/services`) and restarted apache with `apachectl restart`.
  
  That did the trick!
