I've been an active Stack Overflow user for more than a year. As of this afternoon, I cannot log in to either Stack Overflow or Meta SO. The error message says my Open ID is not associated with an account. I'm not sure how I got into this state.
I have only one Open ID. I've only ever used it for SO and Meta SO. I have tried from multiple computers and browsers.
I clicked the "Forgot your login information?" link and had SO send me the Open ID link again. Using that link, I'm prompted for my info and successfully log into my Open ID account, but SO still claims that it's not associated with a Stack Overflow account.
Please explain how I can get this fixed?
I cannot ask this on Meta, because you cannot ask on Meta without logging in.
