Remove Double trailing slash - open cart

Question

i have been contiously upgrading my htaccess file. however, there are 2 issues I just cant seem to fix. I have tried several approaches but nothing really worked for me.

1. my website: https://www.zeroohm.com/

2. my questions:

   • How can I remove the extra trailing slash when i go to zeroohm.com currently, if i go to zeroohm.com, it redirects to https://www.zeroohm.com//

   • if i go to www.zeroohm.com/robots.txt/ , it stops me from viewing my robots.txt file (an error occured while processing this directive). how can i fix this? this problem happens to sitemap.xml and it is causing problems with webmaster tool too. C. any ideas on improving my re-directs?

3. my htaccess file

You can keep these rules in your site root .htaccess:

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^(?:www\.)?zeroohm\.ae$ [NC]
RewriteRule ^ http://www.zeroohm.com%{REQUEST_URI} [R=301,L,NE]

# check if url has www or not, add www if not available. if avaiable don't do anything.
RewriteCond %{HTTP_HOST} !^www\. [NC,OR]
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [R=301,L,NE]

#force trailing slash     
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(/$|\.) 
RewriteCond %{REQUEST_URI} /+[^\.]+$
RewriteRule [^/]$ %{REQUEST_URI}/ [R=301,L]

#libwww-perl security fix
RewriteCond %{HTTP_USER_AGENT} libwww-perl.*
RewriteRule ^ - [F,L]

RewriteCond %{THE_REQUEST} \ /index\.php\?_route_=?([^&\s]*)
RewriteRule ^ /%1? [R=301,L]

RewriteRule ^sitemap\.xml$ index.php?route=feed/google_sitemap [L,QSA,NC]

RewriteRule ^googlebase\.xml$ index.php?route=feed/google_base [L,QSA,NC]

RewriteRule ^download/ /index.php?route=error/not_found [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js|css)
RewriteRule (.*) index.php?_route_=$0 [L,QSA]
