Hamburger menu and search bar not working on mobile. Please help.

Shopify Discussion

Topic summary

Primary Issue:
The hamburger menu and search functionality fail to work on mobile devices, preventing customers from accessing navigation menus.

Root Cause Identified:
The problem stemmed from third-party apps causing severe page load delays. JavaScript required for the hamburger menu was being delayed until after page load completion.

Troubleshooting Steps:

  • Initial suspicion pointed to popup apps interfering with menu functionality
  • Google PageSpeed analysis revealed massive slowdowns
  • TipTop - TikTok shippable app code was removed (didn’t resolve issue)
  • Solution: Removing Scorpio Lab tracking code from theme.liquid file fixed the problem

Resolution:
Deleting the problematic Scorpio Lab code line restored hamburger menu functionality and significantly improved page load speed.

Additional Cases:
Two other users reported similar hamburger menu issues:

  • One case showed no problems upon external testing, suggesting localized or intermittent issues
  • Another case (Talkigapp) remains unresolved with menu not displaying pages on click

Key Takeaway:
Third-party app scripts and tracking codes can severely impact mobile navigation performance. Systematic app removal and code cleanup may be necessary.

Hi there, @Danmuges !

I was able to visit your site and use the hamburger menu with no issue from my location.

If you do have any apps or code edits that are in place for your menus or homepage, that is where I would recommend you start troubleshooting to see what might be causing this issue on your end.
