The only instructions I found was on this link:
http://auctionlisterpro.com/Download
But I have a question about # 3...What does it mean 'OUTSIDE' of your web root...that is, where is this file placed if not in the root?:
**ALP 0.5.3 Installation Instructions
You need to have your eBay Sandbox Keys and Token. If you don't know what this is or don't have them then search on the website to find the article on how to get them.
1.Download and unzip the latest image of ALP from http://auctionlisterpro.com/
2.Unzip the image to your local hard drive.
*3.FTP the files to a folder on your webserver “OUTSIDE” of your web store root.*4.Run the installer located at http://www.mystore.com/alp/install
5.Follow the on screen prompts. If you are not sure what something is then click the question mark (?) for further information.
6.When installation has completed make sure you remove the folder /alp/install
You will need to create an .htpasswd file to protect this installation. When you want to list your products on eBay simply go to http://www.mystore.com/alp**
Thanks!
