Can't log in on my Facebook account any more

[jdh-au]

HI all!

This has been happening since yesterday. I can;t log into the application / mobile app, it's saying 'invalid suername or apssword', even though I'm logging on using the facebook account (premium) I've been having for at least two years now.If I try to log on through the website to check my profile and subscription status (should be fine, am on a year premium code which I activated only a week or so ago), I get a 'too many redirects' browser error.

Pleas ehlp as currently I can't do anything.
