possible Defender and BP group Chat conflict ?

if all ‘hardening’ options are turned on in Defender it seems to prevent BuddyPress Group chat from loading.

if i delete all the .htaccess files that i can find that seemed to have been created by Defender and deactivate Defender then the Group chat opens fine.

i was also having other strange issues with chat such as only the ‘wordpress AJAX’ being available and not the ‘plugin AJAX’ etc.not sure if they are all related but can i request some investigation and advise on these two plugins please ?

kind regards.
