Can't log in to Facebook due to error messages?

All of today I've been unable to log into my Facebook account, on all devices. The message which usually comes up says either 'incorrect password' or that there's some sort of error, so I've gone through all the steps Facebook recommend, e.g. changing my password, getting one-time codes over email/text messaging etc.... but still no luck. Even when I try signing in with the new password, I still have no luck of getting in.

What I also find confusing is that the messenger app on my phone works fine! So I'm still able to Facebook message people... I just cannot get onto the actual site whatsoever, so I'm pretty much locked out. I was wondering if anyone had any solutions towards this sort of thing happening? Or if it's an issue on Facebook's part and not mine, and that hopefully it'll be fixed very soon? I've tried everywhere I can to look for answers on how to fix this but have had no luck, so it'd be greatly appreciated if anybody would be able to help; thanks in advance!
