Yes, In below link:

http://docs.abantecart.com/pages/quickstart/checklist.html

In those link, it is mentioned that this link:
yourdomainname.com/index.php?s=your_admin

will bring us to your Admin Login Panel.

and I said NO.........

the correct one refers to below link:
yourdomainname.com/index.php?rt=index/login&s=your_admin

that will bring us to Admin Login Panel.

When I choose the first link, it will direct me to my own website not admin panel.

I HOPE SOMEONE WILL CONFIRM AND SUPPORT THIS.

THANKS.

(Note: I deliberately do not mention "http://" because when I use it, I can not post this)
