sorry for my bad english

ModRewrite is already available, there's probably some issue with the .htaccess file. Could you please post here its content?

Code:

---

#AddType application/x-httpd-php54 .php .htm .html

IndexIgnore *

<IfModule mod_rewrite.c>

    Options +FollowSymLinks
    RewriteEngine On

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

<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</IfModule>


# # av:php5-engine
AddHandler av-php54 .php

---

Remove IndexIgnore and add a RewriteBase directive. Like this:

Code:

---

<IfModule mod_rewrite.c>
    Options +FollowSymLinks
    RewriteEngine On

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

<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</IfModule>

# # av:php5-engine
AddHandler av-php54 .php
