Persistent "Leave site? Changes you made may not be saved." Issue Everytime Customer Changes Pages

Topic summary

A Shopify store owner reports that customers encounter a “Leave site? Changes you made may not be saved” browser warning when navigating between pages on their site. This affects all visitors across different browsers, indicating it’s not a client-side issue.

Suspected cause: The problem appeared after installing an Omnisend popup. While the popup has been disabled, the warning persists.

Troubleshooting attempts:

  • Another user offered to inspect the site code at wildharvestco.com.au
  • The helper could not replicate the issue, suggesting it may be browser-specific or intermittent

Current status: The problem remains unresolved with no clear solution identified. The warning typically indicates JavaScript detecting unsaved form changes, suggesting residual code from the Omnisend integration may still be triggering the browser’s native alert.

One commenter expressed frustration about this type of technical issue affecting business operations, though their concern appears more general rather than experiencing the same specific problem.

Hello,

I am having trouble replicating the issue. Is it now fixed? If it is still showing up for you, what browser are you using?
