Почему мой .htaccess не работает на этом VPS?

У меня есть следующий файл .htaccess в /public_html/.htaccess:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Вот разрешение моего каталога public_html / на сервере Ubuntu 14 Wordpress 4.1 Apache 2.4 У меня есть почти идентичные сайты Wordpress с тем же файлом .htaccess, я не понимаю, почему я получаю ошибку 404 на моих страницах Wordpress - Примечание. Я могу видеть домашнюю страницу моего веб-сайта, но всякий раз, когда нажимается ссылка, возникает ошибка 404, в прошлый раз, когда это произошло, я обнаружил опечатку .htaccess, на этот раз я не уверен ..

Мои журналы ошибок и доступа имеют одинаковые разрешения, я вижу журнал доступа, записанный при посещении сайта, но без ошибок ни в журнале ошибок, ни в error_log в каталоге Wordpress public_html /

/log$ ll
total 336K
drwxr-xr-x 2 www-data root 4.0K Jun  6 18:17 .
-rw-rw-r-- 1 www-data root 1.6K Jun  9 14:14 error.log
drwxr-xr-x 6 www-data root 4.0K Jun 10 07:23 ..
-rw-rw-r-- 1 www-data root 320K Jun 10 07:42 access.log

Я не вижу ничего, кроме заметок журнала от перезапуска apache2 в журналах доступа и ошибок / etc / log / apache2

Я подозреваю, что проблема теперь связана с AllowOveride All в моих файлах конфигурации, поэтому я обновил их всеми возможностями, но все еще получаю ошибки 404:

cat 000-default.conf 
<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

    # For most configuration files from conf-available/, which are

Я также попытался изменить файл .htaccess, обратите внимание, что я увеличивал редактирование построчно, ни одна строка не изменилась за пределами оператора if.

cat .htaccess 

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

В моих журналах ошибок по-прежнему ничего нет, мой синтаксис верен 000-default.conf и foobar.conf файлы? Я использовал https://askubuntu.com/questions/429869/is-this-a-correct-way-to-enable-htaccess-in-apache-2-4-7-on-ubuntu-12-04
