AH01630: client denied by server configuration Apache
Solution 1:
Apache 2.4 comes with some security enhancements that attempt to make it more difficult for hackers to hide their files on a compromised system. This behaviour is explained more at: http://httpd.apache.org/docs/2.4/upgrading.html#access
A quick easy fix is to add a directory rule to your main apache config file (/etc/apache2/apache2.conf by default on Ubuntu):
<Directory /path/to/my/sites>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
