I did changes in the .htaccess file 5 months ago.
Изменения в файле .htaccess я делал 5 месяцев назад.

I think that the company the owner of a hosting made some changes on a hosting though they also won't confess in it. I saw on a hosting there were new functions and new folders, just that day when my site ceased to open. And this code in the .htaccess file ceased to work normally.
Я думаю, что компания владелец хостинга внесла какие-то изменения на хостинге, хотя они и не сознаются в этом. Я видел на хостинге появились новые функции и новые папки, как раз в тот день, когда мой сайт перестал открываться. И этот код в файле .htaccess перестал нормально работать.
