Plugin Issue

So today, when i was arrived at home after doing some activities in Campus, i get some serious problem to faced tonight, such as;

1. Can not login
   So, i use some Captcha plugin for login page to reduce some boots login attemp. But unfortunately this plugins can not loaded. So you can imagine i'm trying login hundred times to login with right ID and Password without playing the captcha. Yes, that was useless.
2. XML does not works
   Few weeks ago, i get some recommendation from my friend about fast-and-good-security of Wordpress. I followed the setup plugins instructions and everything is done. But somehow i try to make some 'innovation' and... Boom, everything goes wrong, XML pingback does not works and it cause long time loading and i did not receive any Visitor information.

So, because of this issue, i was forced to directly delete this plugin directly from cPanel. And yeah... If your loading is not ending please clear your browser cache and cookies.
