I’ve checked your site and I don’t see the CSS code on inspection.
I see that you’re using a caching plugin. Perhaps disabling or purging the cache will show an updated version of your CSS codes. Can you try disabling the caching plugin or purging its cache?
It’s not there atm, I disabled/removed it, because having the entire right sidebar sticky didn’t look alright.
I know what I did wrong previously. I removed
.site-content {
display: flex;
}
because it kinda messed up my site structure, because I have floats. I now added the “flex” and introduced “margin-left” to the sidebar, so it is working once again.
