after i set up the rewrite rule to rewrite non www to www, and whenever I try to connect to phpmyadmin, i will get the "No input file specified."
below is the rewrite:
if ($http_host != www.example.com) {
rewrite (.*) http://www.example.com$1 permanent;
}

any idea why this is happening, I spent 2 day googling, still can't find the solution
