Hai,
I was hoping this problem can be solved at next release of wordpress MU because it was always and always not able to upgrade all blogs which i always have following error:
Upgrade Site
* http://xxx.example.com/
Warning! Problem upgrading . Your server may not be able to connect to blogs running on it.
Error message: malformed
My suggestion is if we can skip all the malformed error and upgrade any blogs that don't have error.
Regards,
Wallace
