How to Fix Facebook “Bad Request” Errors

Title Abbreviations Explained Here


I get these Facebook “Bad Request” errors all of the time when entering sweepstakes. I finally decided to figure out what was going on and find a fix for them.

If you get a bad request error it is usually after you enter a sweepstakes but in rare cases I have seen it before I try to enter. It looks like this:

Fixing Facebook Bad Request Errors

Error: Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit

The issue could be a corrupt cookie since it shows the word Cookie in the error – see above. A cookie is a file that is placed on your computer when you visit a site. You can easily delete it without causing any problems.

Clear the cache and the cookies from sites that cause problems.

NOTE: When you delete Facebook cookies it will log you out of Facebook and you will have to log in again. I suggest you delete any cookie that has the word Facebook in it.

I also suggest you search and delete cookies for the follow apps since they are used to run sweepstakes and could have been corrupted once a sweepstakes has ended. They continue to try to use the same cookie when a new sweepstakes is listed using that app.

  4. I use a Google Chrome extension called Cookies to manage my cookies. You can make a list of cookies you want deleted and just click one button to do it. If this link doesn’t work, just search for the word Cookies in the Chrome web store:
