I have created an account on Stack Overflow created with my Wordpress login, and an email address ending in .co.uk. I have another account used on other Stack Exchange sites that use my Google account. I want to merge those accounts, and use Google for logging in.
I logged into Stack Overflow with my Wordpress account, changed the email address to my Google address, and tried to save (and thus merge), but got this error:
Oops! There was a problem updating your profile: Email is already registered
Do you have any idea on what I need to do?
