No description visible

Dear People,

After following the steps on https://nicolahastings.me/how-to-add-a-gallery-description-in-foogallery/ I can’t still see the description above the Gallery. Additional, I cleared all caches and used several browsers, but no change! But at the backend the description field is visible (https://pic.li/S3GC) After altering the code, my “gallery-default.php” looks like this now: https://pic.li/S2ji . Did I miss an important step?

It would be great, if someone of you could give me a hint!

Best regards, and thank you in Advance!
