Try using Twentyfifteen with no other plugin activated than WP Idea Stream & BuddyPress.

Just tested on my side everything seems to work fine

As the plugin is installed, not the first time. Now works. I believe that it works perfectly with Twentyfifteen, but I would like to have a plugin that was working on my website. How can I ask you what you would look, properly plugin works for me?
And there is, please, can you do that to your plugins work with this plugin commenting – wpDiscuz?
