I simply cannot log into Facebook. It asks me to change my password which I have done a number of times and still no luck. I do know the email is still good because I had aonther Facebook user send me a message and I received it in that email account.
have you tried to use from any mobile device? it happened to me when i login from my cell phone and when i login by my computer it asked me to change my password.... it will be better to givfe any snapshot of error while logging-in.
have you checked it from anyother system.... try that probably your password has been hacked or any other security threat. you should mail to facebook admin for you complain hopefully they will sort out your problem :)
I can understand that your problem because I have already faced it sometimes Facebook send a message to ask for change the password of your facebook account.
Suppose you have made a mistake while log in your Facebook account then when you login successfully your Facebook account. You will recieved a message from Facebook that ask for change the password. But if you don't want to change your password then skip it.
Just mail to facebook from your email-id and ask them for help in this regard because this is their service issue you have tried all the possible issues at user end but still if you have problem then it is a service issue just send a mail to facebook admin from your mailbox
First of all make sure that you are typing the correct characters of your email address and password.
If the problem not solved then press "forget the password" link and follow the instructions to get your original password.
facebook corporation will send your password in your mail address.
then you can easily log into Facebook.
