I have a site and it's running with
Community Builder 1.9.1 and this version is no longer maintained by their developers. I have
Joomla! 3.4.8 running on my server.
I have seen the changelog and newer version files, it's a very big update including so many changes.
Main issue is
I have to update CB to latest version but some of the core files have been changed in it (I didn't do it). So how I can maintain the same functionality with the latest version?
I am running a site with a really huge number of users so I don't want to take the risk to down whole website for days.
