After setting up your navigation menu, you notice your sub-menus are not appearing on hover, even though they are correctly setup in the menu manager.
- Begin by deactivating all plugins other than WooCommerce, if used. If the menus now work, one of your plugins is conflicting
- Activate each plugin one at a time, reloading your homepage in between to test the menus. When you find the problem, ensure the plugin has been updated, is actively maintained (last update is less than 6 months or within 30 days of a WordPress update) or replace it with a similar plugin.
