Different sign-in pages for Yahoo! mail?

I find that Yahoo! has two different sign-in pages. One page has a single line for your email address, and after entering and clicking, should bring up a page with a line for one's password. That no longer works for me on my chromebook. When I enter my address and click, the indicator at the top just continues to turn slowly until I get a "can't reach" notice. The other sign-in page has two lines, one each for email address and password, and that page gets me into my account and email. My problem is that this two-line page almost never comes up, and I'm not able to sign in. Can anyone suggest a way to either reach the two-line page, or get into my avvount in another way? Thanks!
