my facebook is blank why?

If you’ve created “interest groups” and are experiencing a blank homepage, delete all of your interest groups and then refresh your profile (some users have reported that you only need to delete a few interest groups). It should now display correctly.

Interest groups are different from friends groups. To find them, find the very last section in the left sidebar of your homepage.Obviously, if you’ve been heavily using interest lists, you may not want to delete them but it will solve the problem!
