Why is my 'Add to Cart' button not working on all products?

Topic summary

Add to Cart button not working on some product pages; one product lacks the button while others work.

Findings:

  • On the problematic page, the form shows no submit button. Screenshots highlight the missing control and numerous page errors.
  • The button initially appears on load, then breaks. The working page includes an input type=submit element.

Possible cause:

  • Third‑party interference. A new app (RedBrain for Google Ads) was recently installed; no other interfering plugins were identified.

Clarifications:

  • It’s unclear if the reported errors are from Google Search Console; the errors were observed while the page loaded in the browser.

Actions/Recommendations:

  • Contact the app developer, especially if the issue began after installation.
  • Check whether any plugin/extension is interacting with the product page and breaking the button.

Status: Unresolved; investigation and app developer follow‑up pending.
