Why is my Facebook saying 'session expired' and how do I fix it? or Getting 'session expired' on Face

This kept happening to me too!

I cleared my cookies (not just cache) and it finally stopped. On mobile, go to browser settings and nuke those cookies.

If you’re on desktop, try a different browser to see if it’s just Chrome/Firefox acting up.

FB’s been buggy lately tho, so might not be just you.
