Modify my htaccess

Hi,

I need to modify my htaccess to redirect all of my mobile users to another url, but wordfence doesn’t allow it. It always replace by the original htaccess.

Things I tried:

• Modify the permissions by ftp
• Put the code after, before and between the #BEGIN WORDPRESS
• Tried to put my ip on whitelist on wordfence
• Tried WP htaccess Control to modify via wp admin

And nothing worked 🙁 What can I do?

Thanks in advice
