numbers and no thumbnail carousel?

Hi assisted, how did you end up fixing the problem? I updated and my carousel isn’t working anymore either.

For example – https://fabulush.net/2012/05/2622/

Mine used to work like this: https://talesofendearment.com/dont-try-this-at-home/

and now my galleries just appear as: https://fabulush.net/2012/05/2622/

Please advise and help!
