Problems with FB login and usage

Hello. Since yesterday, I have been unable to log in to my Facebook account the normal way. If I clear my browser cache and other data, I can go to the login page, but as soon as I enter my login information, I either get the error message "Sorry, something went wrong. We're working on it and we'll get it fixed as soon as we can." when on mobile, or just a blank page when I'm on desktop.

If I enter facebook through https://m.facebook.com/login/?next=https%3A%2F%2Fm.facebook.com%2Fads%2Fmanage&refsrc=https%3A%2F%2Fm.facebook.com%2Fads%2Fmanage&_rdr I seem to be able to use the mobile version of Facebook, but as soon as I try to open a Facebook link in a new tab, or enter a FB address in the address bar, I get the same error again. The desktop version I can't get to work at all.

This is happening with both of my computers and my Android phone. Other Facebook accounts work fine, and my account does not seem to be blocked.

I'd thoroughly appreciate any help!
