Warning: require(config/development.cfg.php): failed to open stream: No such file or directory in /var/www/megatour/mega-tour.org/index.php on line 7
Fatal error: require(): Failed opening required 'config/development.cfg.php' (include_path='./:/var/www/megatour:/') in /var/www/megatour/mega-tour.org/index.php on line 7

Answer 1

Do you read errors at all?
The config/development.cfg.php file is missing from the /var/www/megatour/mega-tour.org folder Moral
: always specify absolute file include paths.
And read the error messages at least once in a while.
