Thank you for creating this plugin, it works great!
I have found one issue with it though. If you try blocking several pages as a bulk action it will send you to the "All Posts" page saying this: "3(Or whatever number of pages you tried to block) posts 0.000000e+0d." Then if you go back to the "All Pages" page it will say those pages that you tried to block are now blocked. Then if you look at each of the pages that you just blocked they will say they aren't blocked.
Trying to bulk action block pages currently doesn't work. You must go into each individual page to block them. Can you fix this problem?
