Javascript issue?


I am having a strange problem. I have a web site at, and I was able to access the web site without any problem. but recently, I have that login window that popup each time I access a web page. I did not have any login popup window codes on my web pages, and I did not add or modify my pages for years. Anyway, I called my provider, and they said that they do not see the popup login window. I asked all my friends to access the web site and they all got the popup login window. The only thing I have on my web pages are some Javascript code. Any idea what is going on?
