I'm implementing LiveID authentication on my website. I've done it before, but not on this particular platform, MojoPortal.
The sign-in works properly, but when I attempt to sign-out, I get the error message quoted below. My browser is not blocking cookies.
I get the same message when logging in to and out of, say, MSDN with a LiveID too now. I can't figure out if there's something about my site's programming that is interfering with the sign-out process of LiveID (since I believe that all (recent?) websites get sent a sign-out command) OR if live.com is just having issues lately and this is a coincidence.
Couldn't sign you out
We couldn't sign you out because your browser is blocking cookies. To sign out, close all of your browser windows.
To keep this from happening again, change your browser's settings to allow cookies. If you don't know how to do that, see your browser's help.
Purge the browser's cookie cache. I seem to recall this error can come up if a corrupted cookie gets written to the local cache.
