Broke my multi-install the second I enabled it

Was hoping to allow facebook and other social platforms to use my images with this plugin but as I enabled the plugin on my site, it re-wrote my htaccess file crippling my sites. I immediately got a 500 server error and it took my other site down as well that’s on the same multi-site install even though I enabled the plugin on only one of the two sites.

Do yourself a favor before you try this on your install and backup your htaccess file and be logged into your ftp so you can quickly swap back to your backup htaccess file if this does not work on your install.

The developer definitely still needs to do some work on this.
