Перебрасывает на главную при защите папки паролем через.htaccess - Joomla 3.x: Установка, обновление и настройка

При заходе на "//test.site.ru/administrator" перебрасывает на главную страницу "//test.site.ru".
Скриптов защиты нет. Установлена чистая Joomja 3.9.13.

Перебрасывает после того как закрываю паролем каталог "test.site.ru/administrator/", создав в нём файл ".htaccess" с содержимым:

AuthName "Enter login"
AuthType Basic
AuthUserFile /home/userхxx/.htpasswd
require valid-user

(по инструкции с сайта //joomlatown.net/blog/zaschita-i-bezopasnost/kak-sdelat-basic-avtorizaciyu-cherez-htaccess

При установке пароля на папку "//test.site.ru/admininstrator" через cPanel также выбрасывает на главную.

При удалении ".htaccess" в корне "//test.site.ru" Basic защита запрашивает имя и пароль и всё работает.


Что нужно добавить в ".htaccess" из корня сайта (стандартный файл из коробки)?

RewriteEngine On

## Begin - Rewrite rules to block out some common exploits.
# If you experience problems on your site then comment out the operations listed
# below by adding a # to the beginning of the line.
# This attempts to block the most common type of exploit `attempts` on Joomla!
#
# Block any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
# Block any script that includes a <script> tag in URL.
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
# Block any script trying to set a PHP GLOBALS variable via URL.
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
# Block any script trying to modify a _REQUEST variable via URL.
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
# Return 403 Forbidden header and show the content of the root home page
RewriteRule .* index.php [F]
#
## End - Rewrite rules to block out some common exploits.

## Begin - Custom redirects
#
# If you need to redirect some pages, or set a canonical non-www to
# www redirect (or vice versa), place that code here. Ensure those
# redirects use the correct RewriteRule syntax and the [R=301,L] flags.
#
## End - Custom redirects

##
# Uncomment the following line if your webserver's URL
# is not directly related to physical file paths.
# Update Your Joomla! Directory (just / for root).
