So today I am having this issue as well.
I never had this problem before.
When I log into Yahoo Mail from
http://mail.yahoo.com or from the startsite,
http://www.yahoo.com, the page will not load. Also, when I click on my mail from Yahoo Messenger, it will not load. I've tried using FF & IE. I've cleared all private data, cleared my cookies, etc. I even tried to use Microsoft Outlook, but it did not work.
Anyone else have problems today?
Very frustrating.
I have been trying to use old accounts of mine on other websites, which I (unfortunately) forgot the password to. Of course, I used the "forgot password" link, but it was e-mailed to me! I cannot check my e-mail to find out my old password. Bleh.
