Context does not work in MODX Revo. Where is the mistake?

Question

MODX

Good afternoon.
There is a site on Modx revo. It is necessary to make a variant with 2 languages.
1) Made context settings for 2 languages: English, Russian (eng, web).
Entered values: site_start, culture_key, site_url, base_url
2) Changed htaccess:
# The Friendly URLs part
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(ru|en)?/?(. *)$ index.php?cultureKey=$1&q=$2 [L,QSA]
# redirect all requests to /de/favicon.ico and /nl/favicon.ico
# to /favicon.ico
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(ru|en)/favicon.ico$ favicon.ico [L,QSA]
# redirect all requests to /de/assets* and /nl/assets* to /assets*
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(ru|en)/assets(.*)$ assets$2 [L,QSA]
# redirect all other requests to /de/* and /nl/*
# to index.php and set the cultureKey parameter
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ (en|en)?/?(.*)$ index.php?cultureKey=$1&q=$2 [L,QSA]
3) And created plugin with OnHandleRequest event
<?php
if($modx->context->get( 'key') != "mgr"){
/* grab the current langauge from the cultureKey request var */
switch ($_REQUEST['cultureKey']) {
case 'en':
/* switch the context */
$modx->switchContext('en');
break;
default:
/* Set the default context here */
$modx->switchContext('web');
break;
}
/* unset GET var to avoid
* appending cultureKey=xy to URLs by other components */
unset($_GET['cultureKey']);
}
4) Installed babel and created links between several resources in a different context.
And now the problem: any time you open a resource from another context, it gives a 404 error.
Checked access rights.
In what there can be a problem and with what it can be connected?
