virtualhost - Apache 2.4 on Debian issue - "Forbidden" after upgrading virtual host

I have tried many suggestions I can find via Google to make my virtual host work properly after upgrading from Debian to Jessie (upgrade from Apach 2.2 to 2.4).

I have mod_rewrite and mod_access_compat, which is why it seems to work fine when I use the old syntax. As soon as I go to Require all granted, it stops working and I get 403 Forbidden.

I have many virtual hosts and it's the same accross the board... most are Drupal installs. Here's an example of a virtual host:

    ServerName www.skyjacobs.com
    Redirect 301 / http://skyjacobs.com/


    ServerAdmin skyjacobs@gmail.com
    ServerName skyjacobs.com

DocumentRoot /www/sky

        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny  # These 2 lines work 
        allow from all    # 
        Require all granted   # If I use this line only, it stops working

    ErrorLog /www/logs/sky/error.log
    LogLevel warn

    CustomLog /www/logs/sky/access.log combined

If I comment out the 2 lines of old syntax and use Require all granted, it stops working. Does anyone know what the problem might be? Thanks for any leads.
