Please make sure that you received this request at an email address that is listed on your account. If the request was sent to a different email address then it will not show in your account.

In addition, if someone deactivates his or her account, you will not see the friend request on your Home page.

Follow these tips to troubleshoot your issue:

1. Make sure you have not adjusted your Notifications Settings.
2. Check your spam or junk email filter to make sure that emails coming from Facebook aren't being placed in this folder. If they are, be sure to add the @facebookmail.com email domain to your email account's safe senders list.
3. If you're still not receiving emails from Facebook, please contact your ISP (Internet Service Provider) to ensure that they are not blocking email traffic coming from Facebook.
4. If the issue continues, please report it to us.

Most likely, this person removed the content from your profile (timeline) before you were able to view it. Unfortunately, there is no way for you to view content after it's been deleted.
