There is an article with the address site.ru/article/article-name
If you enter site.ru/fdfdggg in the address bar, then everything is OK, it will redirect to 404,
and if you enter site.ru/article/article- name/fdfdggg then a link opens with the article site.ru/article/article-name
How to set up the correct operation of 404 in Bitrix?

Answer 1

I'll answer myself. In my case, the problem was solved by adding a rule to .htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !/bitrix/urlrewrite.php$
    RewriteRule ^(.*)$ /bitrix/urlrewrite.php [L]
</IfModule>
