Hi there,
try this PHP Snippet:
add_filter( 'generate_sticky_navigation_logo_output', function($logo) {
if ( ! is_user_logged_in() ) {
return;
}
return sprintf(
'<div class="sticky-navigation-logo">
<a href="%1$s" title="%2$s" rel="home">
<img src="your_logo_url" class="is-logo-image" alt="alt name" width="100" height="100" />
</a>
</div>',
esc_url( apply_filters( 'generate_logo_href', home_url( '/' ) ) ),
esc_attr( apply_filters( 'generate_logo_title', get_bloginfo( 'name', 'display' ) ) )
);
} );
You will need to update the src and other attributes in the img tag.
