I have on my Site some specific Modules that was programmed especially for me. But when i install the new Version of JS when my Modules dont work anymore..... How i can update and my Modules still work?
Any custom modules that were written to integrate with Jomsocial would need to be updated to work with current releases. This is normal as code changes and features are added. If you are not able to contact the original developer to update them for you, You may find this link helpful
