Laravel 5 需要 index.php 使用 Apache 虚拟主机

When I load pages that are not root, the page won't load without index.php before the route. The error I get:

 Not Found

 The requested URL /login was not found on this server.

 Apache/2.4.7 (Ubuntu) Server at mydomain.com Port 80

To start with I have a virtual host file containing:

//also tried adding DirectoryIndex here before <directory>
<directory /var/www/mydomain.com>
    DirectoryIndex index.php
    AllowOverride ALL
</directory>

还有一个.在我的公众中访问:

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # Redirect Trailing Slashes...
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

I have another domain with the same .htaccess and appache config on the same server and it works fine. Also I did restart apache. If I use phpinfo on my index.php/route page I see at Loaded Modules:

mod_rewrite mod_setenvif 

When running the website localy with xampp everything works fine. For hours i'm trying now but I can't fix it or find any error (logs are empty) or any solutions that I haven't tried yet.

Edit:

Im using Ubuntu Ubuntu 14.04 x64 on a digital ocean VPS. And I tried turning it on and off again (as suggested). PHP Version 5.5.9-1ubuntu4.9. I followed this tutorial to config everything (except the direcoty part). I changed the location of the apache log and a file error.log is created on the given directory but no errors are in it.

我当前的Appache配置是:(我已经三次判断了域名所在的白色部分).

当我运行apache2ctl-t D DUMP_VHOSTS时

这在我看来很好，我也试过禁用默认配置，但没有帮助.

Note: i've replaced my real domain with mydomain.com in reality I use my real domain on these spots.

Thought how do I know for sure that the conf file im editing is the one being used by the domain?
