 * For some reason, the function below in my functions.php in theme folder seems
   to cause blank pages on saving anything in the admin section. Anyone got a idea
   what is causing this problem?
 *     ```
       <?php
       function catch_image() {
       	global $post, $posts;
       	$first_img = '';
       	ob_start();
       	ob_end_clean();
       	$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
       	$first_img = $matches [1] [0];
       	if(empty($first_img)){
       	$first_img = "/images/default.jpg";
       	}
       	return $first_img;
       	}
       ?>
       ```
