I was going through my saved passwords in Safari to make sure they're all secure and all of a sudden, they all reset back to an older version. This means the ones that have been changed are now the old version (which is weird because that means they were saved somewhere even though I had updated them) and the ones that were new are now completely gone. Why has this happened? What can I do? Right now I'm pretty much logged out of everything. I appreciate your help.
