Warning: Cannot modify header information - headers already sent by (output started at /home/ddubuque/public_html/mod/install.php:146) in /home/ddubuque/public_html/index.php on line 315

1) Your script is trying to use shell_exec() to execute a command via the command line, which we don't allow on Free Hosting. You will need to find that line in the script and figure out how to run whatever it is trying to run manually via the web
2) for the 500 Internal Server Error: check file and folder permissions, files should be 644 and folders should be 755. anything 666 or 777 will cause errors. Second, check .htaccess files and remove any mention of php_flag, php_value, etc.
