Why cant I log into facebook?

Probably a Cache and Cookie problem. Clean both those items the go to Facebook by using this address in your address bar m.facebook.com and you should be able to log in.

This happened to me last week. I did a search first and learned of the Cache and Cookie problem and was able to log in with no problem after cleaning them.

If you signed up for the verification code be ready to go to your phone and get the code to get logged in. Once the cache and cookies are deleted Facebook may not recognize your browser and may require the verification code.
