Hello, I previously registered an account with my email and upgraded to Level 3. I was suspended for a while due to some things, but recently I cannot log in successfully. The specific situation is that after I entered the previous account and password and clicked "Sign In" when I logged in, the web page did not redirect and failed to log in successfully. I think that my github account is also associated with an email, guessing if logging in with github can also synchronize my previous email address. So I finally successfully logged in with my github account, but my level is now Level 0. I have tried to log in to my original email account several times on different computers, but the web page still does not redirect. I didn't find the official email, so I posted my question here and asked for help. Thank you.
