ISSUE SUMMARY:Jomsocial back end opens with white screen of death. I would wait on this one, but the difference here is I am running PHP7. With Joomla 3.6, jomsocial 4.2.2. So you may want to look at it.
I have downloaded patch for core but see that it is for php5 I think so was not able play with it.
Following errors are:

Warning: require_once(/home/peppy/public_html/components/com_community/models/community.php): failed to open stream: No such file or directory in /home/peppy/public_html/components/com_community/libraries/core.php on line 672

Fatal error: require_once(): Failed opening required '/home/peppy/public_html/components/com_community/models/community.php' (include_path='/home/peppy/public_html/plugins/system/shlib/shl_packages//ZendFramework-1.11.7-minimal/library:.;/path/to/php/pear') in /home/peppy/public_html/components/com_community/libraries/core.php on line 672


STEPS TO REPLICATE:
1 log in to joomla administrator
2 Go to Components
3 Go Jomsocial
4
5
RESULT White screen of death
EXPECTED RESULT: Jomsocial back end configeration
BROWSER: Opera, chrome, firefox
