Something wrong with my home page slider

Hi,
I've placed my store on a new url and somehow my home page slider is gone. I only get this: <?php echo $banner['title']; ?> with an empty image tile in front of it. After trying to make a new slider and putting it on my home page (didn't change a thing) I would like to hear if someone had an idea on how to fix this.
Thanks for reading my question(

Dit you change your config.php files, to match the new server path?
