I fixed it ... but for that i had to change my document root setup

when i was using /home/servergreek.com/public_html/www i got "no input file specified"(although the directory existed and had index.php in it).Then i did a server reinstall again but i choose /var/www/servergreek.com/public_html/www . But why the /home/servregreek.com/public_html/www didn't worked?

Btw i created both directory as shown (i did no chown on either on them)

mkdir -p /var/www/servergreek.com/public_html/www -worked
mkdir -p /home/servergreek.com/public_html/www - didn't worked


Is an extra step required when using directories outside /var/www ?
