Hover-cursor issue and links that don’t work without footer


I have an issue, and I don’t understand what’s wrong.
I’m pretty sure it’s an easy task but I’m confuse, I don’t get this issue :

All the links of the page DO NOT work if I delete the section Footer.
Why ? I don’t know. So I have my Footer Final section, that I use, and the Footer section with nothing inside but I can’t delete it or every link won’t work?

Other thing, pointer cursor doesn’t work, at all.

Any help would be appreciated.
Thank you very much and have a nice day.

Here is my site Read-Only: Webflow - Acontios

It sounds like a z-index issue.

I don’t see where it could be this issue?
