• from the instructions I understood that I have to rename the "Admin" to match the name of my "Modified Admin" then upload using filezilla the renamed "Admin" folder to my renamed folder on my site including the "zencart 1.5 extra files".
but when I did that I a new "renamed Admin" folder appeared under my "Admin".
From my other installs it has never creadted a new "Admin" under the original "Admin"
