Thank you.
moving the admin path is not easy
I saw it. 
but actually not necessary (security by obfuscation ;)). Just take care you secure it via a .htaccess.
Not every hoster allows every command within the htaccess or if the client (web shop owner) has a dynamic IP, then … you have discussions.
To rename the backend path is therefore much easier.
Since a couple of years we work with Zen-Cart.
This application comes “out of the box” with this “feature” and during install process the admin/integrator must rename this path.
Could this be an option for OXID as well? This will enhance security without much effort and shop owners have a better sleep.
