Answer 1

Server:

# 301 редирект со страниц со слешем на страницы без слеша в конце URL
rewrite ^/(.*)/$ /$1 permanent;

Answer 2

This is the construction that works in htacess for Latin URLs. It did not work with Cyrillic (( Like the answer above, it also did not work with Cyrillic in the URL
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^(.+)/$
RewriteRule ^(.+)/$ /$1 [R =301,L]

Answer 3

to display a widget in a column, you can use the content property of the column class
