EXPECTED RESULT
A working iJoomla Installer module and a working upgrade module and a performant licensing system especially for professional subsciptions . Why else would we need the iJoomla Installer??
if still not working you can install jomsocial directly by download the newest jomsocial package from "my account" page and install the jomsocial zip package directly.
ijoomla installer is not working for some server case, seems your SSL server use the old version, but our developer is still checking this.
Issue was due to iJoomla installer and is fixed now.
Fix:
1. Download and extract the JomSocial package
2. Upload and install only package "iJoomla-Installer-Updater.zip" using the "Extensions/Manage/Upload Package File" menu
3. Go to iJoomla installer (you'll notice a new icon) and upgrade your version as usual (you might click the upgrade button twice)
