title: HTTP 500 error when logging in facebook on web or mobile
body: <p>I have been getting this error message the past 36 hours. Facebook support has not been any help at all when it comes to resolving this issue. I've cleared my cookies and cache multiple times. I've tried from multiple machines as well as my phone. Still no luck on logging in. Is it an error on my part or are they doing maintenance? Please assist, I did not want to have to post here but I have no more options...</p>
