I couldn’t register (still can’t log in) with Facebook, and when I go to my profile page, it’s stuck on loading. Can anyone help?
You could clear your cache and cookies and try again.
I have some possible solutions for you
1) If you are using the Facebook with secure login ( https://www.facebook.com) then try removing 's' from 'https'
2) If you are not using secure login, try using it.
3) clear history including cache from the browser. (https://support.google.com/chrome/answer/95582?hl=en) here is the steps on how to do that
4) Try another browser as told by Honsep A
5) If problem persists, reinstall chrome if you are persistent on using chrome, Firefox works fine with Facebook.
try with another browser to check if the problem persist?
