I just upgrade my wordpress installation to latest version. But with new version I lost the ability to change theme for my wordpress as I am using GoDaddy hosting right now on Windows server. And this server has opendir() php function blocked, and hence I cannot use my theme page. But I modify the wordpress code to have the old code which use dir function to read that theme folder and it works fine atleast for now.

Now I install new theme, thanks to its designer Mukku. Hope you all like the new theme.
