Login

I just installed wordpress on a new domain. I’ve been using it on a previous domain for months, so I pretty much know the basics. The installation was easy and good. But I went to login to admin panel for a second time to make a second post, got the login screen (which I never got before because it just automatically logged me in). I put in my info, and click login, and it takes me to a blank page and just stays there. Or does nothing at all. The information is correct because when I try a new password, it says “incorrect password.” What’s the problem?
