You did not specify the file name clearly on your site and also you do not have a zip file there. you have a tar file and I don't know if joomla will install that file extension

My first review and I will say this is too good to be free.
A fantastic module that does exactly what you want it to do for you.

Joomla is great and you guys are fantastic.
I was able to put all my cpanel login forms online thanks to this module
