Locked out after upgrade

I upgraded to 0.77.3, and now I can’t login into hassio.
I try to use Legacy password, but nothing happens when I click the button.

Seems like something goes wrong when loading the login form.

This is how the page looks like:

Anyone got the same problem?

Try deleting your cache/website/clear browsing data settings and then loading again…

Swedish translation has issue, which I fixed few days ago, and it will be released in 0.78

Try to switch language to English or try our 0.78 beta.

Tried that many times, no effect I’m afraid…
Thanks.

Aha.
How do I switch to English when I can’t login?
Any tips?
