I see…
My next tip ![]()
Now I checked it with the other site too. I think the new changes with sidebar might cause this.
https://community.couchers.org/ this is an older version which not contains sidebar codes.
.sidebar-wrapper has a height:calc(100vh - var(--header-offset)) I think this push the content while you scrolling if header is not sticky.
You can set the height: 0; or display: none
#main-outlet-wrapper .sidebar-wrapper {
display: none;
}
