It is a bit of an odd one. The site was only built this year and it has both the free Elemntor and Pro versions installed.
I have inherited three sites that are built in the same way, mostly with Elementor and then the footer is done with ACF Pro. I can see a couple of functions added to the WordPress editor that are very specific to each site so I guess that is where ACF comes into its own. But I cannot see why it would have been used for the footer.
Anyway, thanks to your help I am a lot wiser now. It is really appreciated.
