My footer has disappeared

Hello, I edited a footer’s code to say that the site was designed by me. However now, I cannot see it. I built it using Divi 2.7. Please help.

https://www.newtonscabco.com – It’s not here
https://www.merlzart.com – But it’s here

https://www.freedomadministrativeconsultingservices.com – I edited it in this one and it was fine, although I built this site with Divi 2.6. Not sure if that’s the problem.

Please help.
