Ok, I am very new to web development, so excuse that. I set up my webserver using a Linode Stackscript (LAMP). However, my webpage doesn't display my actual index.php file, instead, it displays http://www.imgbomb.com/i/?lBqKe. Why is this? My index.php is inside my www. When I type /index.php after the url, I get a the page you are looking for is not found.
You should add DirectoryIndex index.php to your .htaccess file or webserver configuration file.
