Site does not detect index

Question

I am working on Ubuntu 14.04.2 Apache 2.4.7

I have a virtual host configured to serve files from /var/www/dev, and the configuration file looks like this dev.conf::

<VirtualHost *:80>
    ServerAdmin ubuntu@12.234.567.89
    DocumentRoot /var/www/dev
    ServerName dev.site.com

    <Directory />
            Options FollowSymLinks
            AllowOverride All
    </Directory>
    <Directory /var/www/dev/>
            Options -Indexes +FollowSymLinks
            AllowOverride All
            Require all granted
    </Directory>
</VirtualHost>

I have several files in the directory /var/www/devthat I do not want to index, so the option-Indexes

However, I have a wordpress installation and I want these files to be loaded correctly in the browser. Index file index.phpand is located in/var/www/dev/

I also have a .htaccess file in the same root directory, which looks like this:

DirectoryIndex index.php index.html
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On

RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RedirectMatch 301 ^/terms-and-conditions\.php$ /terms-of-use
RedirectMatch 301 ^/privacy\.php$ /privacy-policy
</IfModule>

DirectoryIndexshould tell the browser to use the file index.php, but I get a 403 Forbidden error.

I tried:

• Opening permissions recursively change of ownership /var/www/devonwww-data:www-data
• DirectoryIndex index.php dev.conf <Directory /var/www/dev/> - ""
• mod_dir ()
• +Indexes -
• , 403 ,
• apache2.conf , DirectoryIndex
• DirectoryIndex + - , , , , .
