My Android/Wap accounts stopped working 2 days ago. I'm unable to log in even though my passwords and usernames are correct. It says:
Does not match stored session / password may have changed by Facebook for security reasons.
Now it is playing up when I log on on my laptop/PC. My profile picture changes on its own, I can post and get notifications but can't see the replies when I click on them. My friends' accounts seem fine, just mine is affected and I'm getting no response from Facebook or forums/pages and getting concerned I've been hacked now. I'm considering deactivating my account.
What can I do to fix this?
