- JavaScript Conflict: The most common issue is a JavaScript conflict. This can be caused by plugins, themes, or custom code. Check the browser console for errors by pressing F12 and clicking on the ‘Console’ tab.
- Caching Issues: If you recently made changes and they’re not reflecting, it might be a caching issue. Clear your site’s cache from your caching plugin and your browser’s cache.
- Plugin Conflict: A plugin might be conflicting with your menu’s functionality. Deactivate your plugins one by one to see if the menu starts working after deactivating a specific plugin.
- Theme Issues: If you’re using a third-party theme, it’s possible that there’s an issue with the theme itself. Check if the theme needs an update or contact the theme’s support for help.
- Outdated Theme or Plugins: Make sure your theme and all plugins are updated. An outdated theme or plugin can cause compatibility issues.
- Menu Configuration: Ensure that your menu is properly set up in Appearance > Menus, and it’s assigned to the correct location.
- CSS Issues: Custom CSS or certain theme settings can hide or disrupt the burger menu. Check if CSS rules are affecting its visibility or functionality.
- Viewport Meta Tag: Ensure your site’s header includes a viewport meta tag. Without it, responsive designs (like a burger menu on mobile) may not work correctly.
- Check with Default Theme: To rule out theme-specific issues, temporarily switch to a default WordPress theme (like Twenty Twenty-One) and see if the problem persists.
By going through these steps, you should be able to pinpoint and resolve the issue with your burger menu.
