Symptom:
(public)
Problem:
(public)		 For security reasons .htaccess files aren't allowed in the webspace of sites or users. You need to keep in mind that .htaccess files can be used to change the behaviour and settings of Apache and Apache medules like PHP.
Solution:
(public)		 In /etc/httpd/conf.d/bluequartz.conf there is this section:

<Directory /home/.sites/>
Options Indexes FollowSymLinks Includes MultiViews
AllowOverride AuthConfig Indexes Limit

In order to allow .htaccess files in webspace, you just need to change it to this:

<Directory /home/.sites/>
Options Indexes FollowSymLinks Includes MultiViews
AllowOverride AuthConfig Indexes Limit All

As you can see, the word "All" was added to the line starting with "AllowOverride".

Afterwards Apache needs to be restarted:

/etc/init.d/httpd restart
