ISSUE SUMMARY:
Yesterday I upgraded our site to Joomla 3.4. Now I can't enter the JomSocial component from the back end. I get the following error message:

Warning: require_once(/home3/mfaweb/public_html/mfa2/components/com_community/models/community.php): failed to open stream: No such file or directory in /home3/mfaweb/public_html/mfa2/components/com_community/libraries/core.php on line 672
