Hello,
I wanted to change the default admin directory (mysite.com/admin) for more security, to: mysite.com/anythingmoresecure, because, I thought then go to the ftp and change the location of the directory.
I been have to go directly in the options of magento: configuration> advanced> admin, and modify the line "admin" to > "management"
But, the path is not phisic, and I do not find the directory/code to go back.
I have already tried to go modify: main/app/etc/locale.xml but the line is still:
<FrontName> <! [CDATA [admin]]> </ frontName>
And when I log in using: mysite.com/management, it redirects me to 404 (no panel)
And when I log in using: mysite.com/admin, it redirects me to http://mysite.com/management/index.php/admin/ but the phisical directory was not mooved here, = 404
How to go back for location: mysite.com/admin ?
please help me 
Big thanks
