Just to tell that if some people can't log in cpanel even thought their website is working it may be because of some hack , well i don't know but i couldn't login myself and noticed something eird in the adress from the link in ipanel. It direct me to the URL :
I have seen someone else posting the URL with this add of ".suckmeoff" so i think that someone have felt like joking. If you correct the URL removing the ".suckmeoff" you can acess to your Cpanel normaly. Well it worked for me.
