the bug is fixed!

Ok. I'll wait for the error.

https://sync.opera.com/web/ - 40х Error
"Page not found. The page requested could not be found."

Opera developer 32.
To complete the synchronization requires a passphrase:
"You already have data that is encrypted using a different version of the password to your account Opera. Please enter it below."
The fact that I have only one account, and I never encrypt data and never pointed passphrase.
What to do?
