Suddenly no login possible - both Admin and Users - don´t have access anymore

Hello.

The title says it all - I suddenly have no possibility to log in - always get the message "Konnte Dich nicht anmelden. Versuche es nochmal."
After 5 attempts I get banned for 10 Minutes. This problem occurs with all accounts.

Would you need the link to the gallery?

Would you need the link to the gallery?

Yes, please. And (if you have) a test user account will also help.

OMG!! Thank you!

Yes, I had changed the method of logging in (to: log in with email adress) and forgot about it. But now it´s sooooo obvious.
