Мой htaccess:

# MODX supports Friendly URLs via this .htaccess file. You must serve web
# pages via Apache with mod_rewrite to use this functionality, and you must
# change the file name from ht.access to .htaccess.
#
# Make sure RewriteBase points to the directory where you installed MODX.
# E.g., "/modx" if your installation is in a "modx" subdirectory.
#
# You may choose to make your URLs non-case-sensitive by adding a NC directive
# to your rule: RewriteRule ^(.*)$ index.php?q=$1 [L,QSA,NC]

RewriteEngine On
RewriteBase /

# If your server is not already configured as such, the following directive
# should be uncommented in order to set PHP's register_globals option to OFF.
# This closes a major security hole that is abused by most XSS (cross-site
# scripting) attacks. For more information: http://php.net/register_globals
#
# To verify that this option has been set to OFF, open the Manager and choose
# Reports -> System Info and then click the phpinfo() link. Do a Find on Page
# for "register_globals". The Local Value should be OFF. If the Master Value
# is OFF then you do not need this directive here.
#
# IF REGISTER_GLOBALS DIRECTIVE CAUSES 500 INTERNAL SERVER ERRORS :
#
# Your server does not allow PHP directives to be set via .htaccess. In that
# case you must make this change in your php.ini file instead. If you are
# using a commercial web host, contact the administrators for assistance in
# doing this. Not all servers allow local php.ini files, and they should
# include all PHP configurations (not just this one), or you will effectively
# reset everything to PHP defaults. Consult www.php.net for more detailed
# information about setting PHP directives.

#php_flag register_globals Off



# For servers that support output compression, you should pick up a bit of
# speed by un-commenting the following lines.

#php_flag zlib.output_compression On
#php_value zlib.output_compression_level 5



# The following directives stop screen flicker in IE on CSS rollovers. If
# needed, un-comment the following rules. When they're in place, you may have

Создал плагин, назвал как требуется, поставил событие OnHandleRequest
Вывел ссылки сниппетом [[BabelLinks]]
Теперь при переходе на monterart.com/en/ выдает 404 ошибку, подскажите где я ошибся, и куда смотреть чтобы исправить

<?php
// Работаем только на фронтенде и только с friendly urls

$alias = $modx->getOption('request_param_alias', null, 'alias', true);
$request = &$_REQUEST[$alias];

// Выбираем контексты с настройкой base_url

			// Вырезаем base_url из запроса, чтобы MODX нашел ресурс по uri
