My site http://www.lightafterdarkness.net/ is extremely slow.
Tried Pingdom Website Speed Test, it never finish loading the page.
I deleted .htcaccess file, it would turn good for some minutes, but turning inaccessible again quickly after several minutes.
I've already installed W3 Total Cache and Bad Behavior. My other WP sites hosted on the server looks good, and this site used to be working well two days ago. I didn't change anything on it. Help!
