web server error logs: [Sat Apr 24 21:06:56 2010] [error] [client 216.110.94.227] Premature end of script headers: index.php
Tried other templates, other versions of Virtuemart, changes of directory permissions,got the same results. Because my site uses subdomains, so I guess may be this issue is related to the .htaccess configuration.
Need an expert help me sort this out. Thanks!
