Hi everybody !
In .htaccess I have to add some lines for remove end-slashes:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^(.+)/$
RewriteRule ^(.+)/$ prosto-coach.ru/$1 [R=301,L]

RewriteCond %{REQUEST_URI} ^(.*)/{2,}(.*)$
RewriteRule . %1/%2 [R=301,L]

after adding that lines, the module stops working.
I realy need to remove end-slashes. Please, help me in this question.
