My site doesn’t scroll anymore.

Site URL: https://waamoz.eu/

Hello,

After adding a section on my home, and published my first blog post, the site suddenly stops to scroll down on any pages. The Squarespace assistance told me that possibly is caused by the CSS, specifically by a Ghost Plugin code down at the bottom of the CSS window. I’ve tried to delete it but it didn’t change.

Can someone please help me to understand the reason?

Tks

Add these code on Design > Custom CSS

body{
  overflow-y: scroll !important;
}
