Hello,
I have checked the logo, it is good when I am logged in, and as per your screen, when I am logged out.
Please contact the host support and find out if the SSL certificate has been configured properly for multisite.
In addition, deactivate all the plugins except these ones:
Slider Revolution
WPBakery Page Builder
Woodmart Core
Contact Form 7
MailChimp for WordPress
WooCommerce
Safe SVG
Please switch to the parent theme and check.
If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.
Best Regards
