I have account from a lot of years, yesterday I changed my e-mail - then I get error "User 'berez' is not known here ". All my history was gone to "trash"...
Probably the cause of this situation is that I have changed the email address that contains the "plus" sign - like xxxxxx.xxxxxx+xxxx@gmail.com.
Dear admin, could you help me? Account doesen't exist, but login is still occupied.
