Position the site title

Are you referring to this?

Any chance you can disable SieGround Optimizer and test if there is a conflict there?

I've turned off the plugin, no change.

Give this CSS a shot:

@media (max-width: 768px) {
    .main-navigation .mobile-bar-items {
        display: none;
    }
}

You did it! Thanks, everyone.

Glad we could help :)

Oh, and I just remembered — how can I include the site title in the sticky navigation? It only shows the hamburger and search icons.

Can you activate the sticky navigation first and let me have a look?
