GraphQL query is unauthorized
I am currently getting this error message on Facebook when I first log in. GraphQL query is unauthorized. This query is unauthorized because some fields permission check has failed. I get this whether using Firefox or Safari on my late 2015 IMac useing macOS Sierra 10.12.6 and yes, I know this is an old OS but it is needed for the software that I use and can't update. This just started happening about an hour ago and I was having no problems up to then. I cannot find any answers for this problem and I am awaiting some response from Facebook about the problem. Any insight would be helpful and thank you for your time.
Mac Pro, OS X 10.11
