Be ware of using defender to 'harden' plug-ins.

So apparently one of 'Defender's ways to improve security is to add htaccess files to different directories.

Not sure if there's a secondary conflict also involved, but when I did this it prevented chats from appearing. (WPMU's chat plug-in, not a third party).

Not really needing any support, but wanting to make sure others in the community who may use defender know that if plugins stop working shortly after to check for the htaccess file and copy/remove it and test ot see if it fixes the problem.
