Changed line 25 to get around the missing $controllerName but am now getting an array_slice error
New Line 25
	
	
	
		PHP:
	
	
		$controllerForum->preDispatch('index', 'XenForo_ControllerPublic_Forum');
	 
 
Line still giving error (line 38):
	
	
	
		PHP:
	
	
		$controllerResponse->params['threads'] = array_slice($controllerResponse->params['threads'], 0, $threadsToShow - 1);
	 
 
Can comment out the above line and all is well .. otherwise .. get this error.
	
	
	
		Code:
