Hi
I've got problems with my WordPress installation which I recently updated to the newest version.
My domain is nüt.org which is translated to xn--nt-xka.org (Internationalized domain names, IDN) and my browsers, Firefox and Safari, seem to have troubles with the two dashes in that domain name. As soon as I enter wp-admin, I get error messages (for example because XML comments may not contain two dashed, but that's not the only error).
I'm not sure if it's just my browser or this is really a WordPress bug. It's odd that this worked a few days ago..
To reproduce the error, you could add an xn--nt-xka entry to your local etc/hosts file.
regards
jonathan
