Facebook sharer.php 500错误

Question

At the moment I am attempting to share a link on Facebook without the use of JavaScript or a Facebook app id.

Previously I could have a hyperlink to: https://www.facebook.com/sharer/sharer.php?u=urlhere and Facebook would scrape for og:tags and allow me to share a site.

At the moment I'm encountering a 500 error when I attempt to submit a link that has not previously been crawled by Facebook.

How to reproduce the bug

• Find a new link that you're certain hasn't been crawled by FB. Good examples of this are tweets.
• Attempt to visit https://www.facebook.com/sharer/sharer.php and paste in your link
• Submit the form and see the post preview
• Attempt to submit the post
• If you've used a fresh URL there is a good chance you'll get a 500 error similar to: POST https://www.facebook.com/ajax/sharer/submit_page/ 500 (Internal Server Error)
• If you refresh the page and attempt to submit the same URL again, it will post successfully.
• Once the link has been crawled by Facebook, it works without problems

Anyone having similar problems with this method of sharing?
