How to find out why RewriteRule is not working?

Question

Apache HTTP Server

Hello.
Faced apparently with a banal situation, however itself I can not solve it. You need to rewrite from this URL:

http://domain.tld/index.php?w=650&h=content&i=madam/rdo_map_nazar_1_sm.jpg

On that:

http://domain.tld/650/content/madam/rdo_map_nazar_1_sm.jpg

For implementation in htaccess I wrote the following:

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)/([^/]*)$ /index.php?w=$1&h=$2&i=$3 [L]

In apache2.conf:

<Directory /home/mo45/www>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>

In vhost it is:

<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerName domain.tld
    DocumentRoot /home/mo45/www/rockstar/weazel
        <Directory "/home/mo45/www/rockstar/weazel/">
                Options +FollowSymLinks -MultiViews
                RewriteEngine On
                AllowOverride ALL
                Allow from all
        </Directory>
    LogLevel alert rewrite:trace3
    ErrorLog /home/mo45/www/rockstar/log/error.log
    CustomLog /home/mo45/www/rockstar/log/access.log combined
</VirtualHost>

The following is in the logs:

mod_rewrite enabled , works on other vhosts. The index.php itself works without the rewrite as intended.
I can't figure out what the problem is.
Thanks in advance for your help.

^([^/]*)/([^/]*)/([^/]*)$
The string "650/content/file.jpg" fits this template, but "650/content/dir/file.jpg" does not.
^(\d+)/(content)/(.+)$
