Hello
I'm using Eventum template and helix on my website https://emf2023.org/
However, I have a problem with the upper menu, it dissapears on mobile and also on computer when you reduce the window.
Im' using Joomla 3.10.11. The Php is newly PHP 8 (but with the older version of PHD it did no twork either). I think everything is updated (template, etc.)
Could you help me?
