Jamroom 5 updating problem
Installation and Configuration
It should be as easy as going to:
YOUR-SITE.com/marketplace/system_update
and clicking the UPDATE ALL ITEMS button.
When you click that a pop-over panel will appear (screenshot) If thats not happening check
ACP -> CORE -> SYSTEM CORE -> TOOLS -> SYSTEM CHECK
to make sure your system has no red lights on it. Could be a server issue, but if you've already done updates before, that's unlikely. Also try installing one of the free modules from the marketplace just to check that the communication system between your server and the main jamroom server is working.
