I have success install on my server with Window Server 2008, Apache 2.4 and PHP 5.6.
After setup database, i got 403 which i am not sure because of vhost configuration, or not?

Here is vhost

<VirtualHost :80>
DocumentRoot "c:/dreamfactory-master/public"
ServerName df.i-bitz.co.th
ServerAlias df.i-bitz.co.th
ErrorLog "c:/WebServer/Apache24/logs/df-error.log"
CustomLog “c:/WebServer/Apache24/logs/df-access.log” common
<Directory “c:/dreamfactory-master/public”>
Options -Indexes +FollowSymLinks -MultiViews
AllowOverride All
AllowOverride None
Require all granted
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.$ /index.php [L]

    <LimitExcept GET HEAD PUT DELETE PATCH POST>
        Allow from all
    </LimitExcept>
</Directory>

Please give me the idea.
Thanks in advance,
