Code Appearing at Bottom of Drupal Site

Good Day,

I have been working on my Drupal 7 site for some time now, however, after refreshing the site this time the following code keeps appearing at the bottom of the site

array (‘excluded’ =>
array (
‘uid’ => false,
‘page’ => false,

I am not sure where it is coming from, I am pretty new to Drupal. Could someone please help me!

Thanks in advance

Drupal version:
