Look in the config file for something like the following:

// this snippet is from PhpDig 1.8.8 RC1 //

// this chunk of code NEEDS to be here for security - checks to see that $template is set to a valid value
if (isset($_REQUEST['template_demo'])) {
    $template_demo = $_REQUEST['template_demo'];
}
$templates_array = array('black.html','bluegrey.html','corporate.html','green.html','grey.html','lightgreen.html','linear.html','newspaper.html','phpdig.html','simple.html','terminal.html','yellow.html','gaagle.html');
if(isset($template_demo) && in_array($template_demo, $templates_array)) {
    $template = "$relative_script_path/templates/$template_demo";
} else {
    $template = "$relative_script_path/templates/phpdig.html";
}

// alternatively force the $template value to a valid value
// $template = "$relative_script_path/templates/phpdig.html";
// if using array, set $template = "array";
// if using classic, set $template = "classic";
