I am trying to install an add-on....(I have tried this with MULTIPLE add-ons and get the same result).
I followed the directions:
downloaded the files
uploaded it via FTP to the Public_html
returned to the admin area and clicked "ADD-ONS" > Install Add-On
I selected the .xml from the downloaded folder
hit Install Add-On (screen shot 1)
after hitting the install Add-on...I get this ERROR MESSAGE
What do I put in the "Install from file on Server" field?
