We just checked your website and the mobile menu seems to work correctly for us. Here is a screenshot https://gyazo.com/e4c8126b77af2b043aba2284a24348ea
Could you please clarify how can we reproduce the issue?
Please, disable all plugins that are not related to our theme and provide us with your admin access. We will log in and check what is wrong there. You can leave only the following plugins that are required for our theme:
WoodMart core
WooCommerce
Elementor/WPBakery page builder
As we can see, both websites have a sticky navigation menu on the desktop. But the main website doesn’t have icons added to your menu items. That is why you don’t see anything until you move your mouse over the menu to open it. You need to upload your menu icons via Appearance -> Menus.
