 * The plugin has this code on line 6:
 * `$_GET[base]`
 * This should look like:
 * `$_GET['base']`
 * Notice the quotes around the word `base`. PHP reads this as a [constant](http://php.net/manual/en/language.constants.php),
   but because there is no defined constant with that name, PHP lets you know about
   it by printing the message.
 * It is best to use quotes in situations like this. Things could go horribly wrong
   if there _was_ a constant named “base” defined in WordPress, another plugin or
   your active theme!
