I've cleared my cache and history in Firefox and still cannot login to Stack Exchange sites (Super User, Stack Overflow, etc). The error is the following:
Unable to log in with your OpenID provider:
Error occurred while sending a direct message or getting the response.
- Using Chrome, I can no longer access any Stack Exchange site.
- Using Safari, I can l ogin to all Stack Exchange sites for which MyOpenID was already authenticated/related to.
- Using Safari, I cannot login to newly related Stack Exchange sites (I cannot follow-up on the question that was previously migrated).
