Once I installed wordfence on my sites, all of them were compromised. WordFence opens a floodgate of hackers, and open doors. If you have given this plugin a good review, it is quite possible that you do not know nothing about wordpress or site security. We lost 3 sites so far over this plugin. Specifically pointed out by our hosting companies and other advanced webdevelopers far and beyond wordpress developmental status has pointed out that this plugin causes problems. You will instantly get hacked, it brings in scripts. Stay clear away from this plugin as we will be sharing a magazine article soon to go live about this issue with this plugin. Let Alone that WordFence does not reply to the on going issues that they are aware of, and are avoiding. See forums within wordfence own site by customers of wordfence questioning about fixes to this problem that have repeatedly been avoided.
