Is there a reason why my Webflow navigation instance (burger menu) is not updating in preview or when I publish the site, even after trying multiple browsers and clearing the cache?

If your Webflow navigation (burger menu) isn’t updating in Preview or after publishing, it’s likely due to a component caching issue or a problem with how the navigation is structured in a Symbol or Component. Here’s how to troubleshoot the issue.

1. Check if the Navigation is a Symbol or Component

• Go to the Webflow Designer and see if the navbar (or burger menu) is inside a Symbol (classic) or new Component (Webflow's updated system).
• If so, double-click to edit the Symbol/Component directly. Changes made outside of this will not reflect upon publish unless you modify the actual Symbol/Component itself.

2. Verify Global vs. Instance Edits

• If multiple navbars exist across pages, make sure you're editing the global version (Symbol or Component), not a single-instance override.
• Check for Overrides (used in Components): In the Element settings panel, look for any overridden content that might need to be updated for the burger menu behavior or content.

3. Unbind and Rebind the Component (If Needed)

• If changes to the Symbol/Component aren’t reflecting, try the following:
• Detach the Symbol or Component from one page temporarily.
• Make your changes directly on the detached version.
• Turn it back into a Symbol/Component, and reapply it globally.

4. Confirm Interactions and Navbar Settings

• Open the Interactions Panel and confirm any animations or triggers tied to the burger menu are correctly applied to the visible element.
• Double-check the Navbar settings (highlight the Navbar → Settings Panel) to be sure that Show/Hide menu options are properly configured.

5. Hard Refresh the Webflow Designer

• Use Cmd+Shift+R (Mac) or Ctrl+Shift+R (Windows) to hard refresh the Designer and reload updated assets. Sometimes old assets can persist.
• You can also try logging out and logging back into Webflow, which can reset more persistent session-based cache.

6. Re-Publish All Domains

• In the top-right corner of Webflow, click the Publish dropdown and choose "Publish to Selected Domains".
• Choose all associated domains, not just staging or custom ones.
• Wait for the confirmation that the publish is complete (check the green bar), then refresh your published site.

Summary

If your burger menu updates aren’t showing, the issue is most likely due to editing an instance of a Symbol or Component without updating the source. Always ensure you’re modifying the global asset, recheck Interactions and Navbar settings, and re-publish all domains after changes.
