I log in to Facebook and it asked me to log in again?

[Elly]

I opened Facebook and it opens at the log in page (you know, the first page where you enter your email and password to get into Facebook).
I entered my email and password.
I pressed log in, but the log in page appears again. It asked me to re-enter my email and password. But when I clicked the home logo (the top left), I got my profile already logged in. What is actually going on?
I already enabled cookies on my browser (google chrome, it is.)
I changed my password once and made Facebook logged me out of any devices I've ever logged in to.
Has anybody got the same experience? How can I fix it?
I appreciate any answers relating to this problem. Thanks in advance!

Change browser to, for instance, Mozilla Firefox. If you can log on to Facebook through Firefox, you know that the problem is in Google Chrome somewhere. Reinstalling Chrome might be an idea as well, if you don't know what settings have changed.
