few days ago, my blog still running ok, with www.blogger.com , never had cPanel login password pop up, i also don't know what's that. but just yesterday, i always got this cPanel login password popup, eventhough i can cancel it, but it seems annoying. can i know why i get it and how to make it disappear forever?

I guess you must be (trying to) load something from that realm. Is it something that doesn't work as expected? Don't find the IP number in your source, but it belongs to http://ev1.net .
