Email address does not change permanently
I would like to change my email address in the settings of this community account. To do so, I go to "My Settings", select "Personal Profile" and "Email" and enter my new email address twice in the corresponding text boxes. Then I receive an "E-Mail Address Verification" email and after clicking on the link within this verification email the "Current email" changes to my new email address and everythings looks fine. So far so good.
But, when I logout and want login again, I cannot login with my new email address. Instead I have to login with my old email address and in the settings of this community account my old email address is again the "Current email".
Does anyone know how to change the email address permanently, not only for one session?
Thank you very much in advance.
