Installation Problem

These are the errors I get:

Warning: include(/home/mothergh/public_html/config.php): failed to open stream: No such file or directory in /home/mothergh/public_html/common.php on line 24

Warning: include(): Failed opening '/home/mothergh/public_html/config.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/mothergh/public_html/common.php on line 24

Warning: Cannot modify header information - headers already sent by (output started at /home/mothergh/public_html/common.php:24) in /home/mothergh/public_html/common.php on line 26

Hello... Is anybody here?
