How can I get Facebook to refresh what is shown in the preview?

Facebook keeps the title and image it saw when the petition was first shared. After you change them, the message "Changes saved successfully" has a link that updates the Facebook preview. You can also do it yourself:

  1. Go to page: Sharing Debugger
  2. Log in with your Facebook account.
  3. Paste the address of your petition and click "Debug".
  4. Click "Scrape Again".
