Facebook Checkpoint - Locked out of my account?

[john]

When I go to log in, I put in my login info, and it takes me to a blank page, with nothing on it. It takes me to the URL https://www.facebook.com/checkpoint/

I tried logging in on the facebook app on my phone and it gives me the message, "In order to regain access to your account, facebook needs to open a browser" at which point it also takes me to a blank page. I've reset my password and that didn't help. Can someone please help me??
edit: I posted on one of my friends profiles the other day, something that I suppose could be construed as a picture with nudity, even thought technically I wasn't. But I haven't received any notifications that my account was temp. suspended. How can I get in contact with facebook to find out?

usually you get that page when you break the rules by lying about your age or name, or creating more than one account

there is no way to contact facebook to find out

Here is a post I copied from a blog website:
"It will most likely be a facebook problem. I had a similar problem with twitter a few days ago. Remember you aren't a customer of these social networks, you are their product, so there is no customer service. I have tried to get support from facebook before when trying to claim a page, but never heard back from them."

Plus, my sister wrote to me day before yesterday and said "They" (meaning Facebook) are out to get me. They won't let me post anything and my pics. show up on MY FB wall, but don't show up anywhere else. And they won't let me comment or like. She was REALLY paranoid!
I told her it wasn't just her, that I couldn't even get ON my Facebook last week! It all cleared up. When I Googled that problem with Facebook Google came up with all kinds of problems just like yours and everyone elses! So just hang in there, I think Facebook is just permanately screwed up!

I wish I could help because I've had exactly the same problem for three days too!
I've done virus scans, deleted cookies and cache, changed passwords and attempted to login from my mobile and yet all I get is the blank white page and the url with facebook/checkpoint! Yet my son can access his account from the same laptop with no problems, it seems to only affect my account. Facebook don't reply and I wish I could delete my account but of course I can't without logging in :-(
