Раскомментировал и подправил две строки

Было так

// directory where spaw files are located
$spaw_dir = '/includes/spaw/';

// base url for images
// $spaw_base_url = 'http://mydomain.ru/';

if (!ereg('/$', $HTTP_SERVER_VARS['DOCUMENT_ROOT']))
  $spaw_root = $HTTP_SERVER_VARS['DOCUMENT_ROOT'].$spaw_dir;
else
  $spaw_root = $HTTP_SERVER_VARS['DOCUMENT_ROOT'].substr($spaw_dir,1,strlen($spaw_dir)-1);

Изменил так

// directory where spaw files are located
$spaw_dir = 'includes/spaw/';

// base url for images
$spaw_base_url = 'http://mydomain.ru/';

if (!ereg('/$', $HTTP_SERVER_VARS['DOCUMENT_ROOT']))
  $spaw_root = $HTTP_SERVER_VARS['DOCUMENT_ROOT'].$spaw_dir;
else
  $spaw_root = $HTTP_SERVER_VARS['DOCUMENT_ROOT'].substr($spaw_dir,1,strlen($spaw_dir)-1);

Выскакивает вот такое.
