Update..
I have no cache related files/plugins/etc.
I have disabled all plugins one at a time and none were causing the issue.
The issue appears to be related to the inFocus_BuddyPress_Child_Theme which has replaced inFocus as a solution – it is not working either.
bbPress is working fine with WP 2012, 2013, 2014 themes and BusinessPro theme.
Anyone resolve this issue with inFocus or know how to troubleshoot/customize the theme?
I have the same issue of not seeing replies.
Based on this thread I uninstalled WP Total Cache plugin.
Also I found w3tc-config folder via ftp and deleted that.
I looked in wp-config and did not see any references to caching.
I still cannot see any replies. Any ideas? Thanks.
