Hello I'm receiving the following error message every hour (I've taken out the address for security reasons and replaced it with '*'s), is there any one that can point me in the right direction for fixing this,

PHP Warning:  require_once(__DIR__/composer/autoload_real.php) [<a

> href='function.require-once'>function.require-once</a>]: failed to

> open stream: No such file or directory in

Many thanks for your help.
