i think this error is just caused by a missing file. But there should be some kind of error checking here to not crash the whole site just due to a missing image file.

this error is quite hard to find where its actually coming from as its within a library file on another page so it does not really tell where the error is coming from.

I guess first ill check if the image does exist. 

Nope the image does not, but its weird that passing an invalid file crashes the whole page.

it seems this is causing the error

content.class line 144

PHP

$img = new bones\SimpleImage($local_file);

so should just add a check for the $local_file existing before running it through simple image and that should fix it. 

PHP

					if(file_exists($local_file)) {
	                	include_once("lib/SimpleImage.php");
	                	$img = new bones\SimpleImage($local_file);
	                	$img->thumbnail(165, 165)->save($thumbnail, 70);
					} else {
						$thumbnail = "";
					}

check if the file exists and if it does not set the thumbnail to blank or a placeholder probably.
