If one of your button CTAs leads to a warning page, it's likely due to a malformed tracking URL. When you create a button CTA, HubSpot will validate the domain of the tracking URL to confirm that it aligns with the domain you connected.
If that button CTA's original tracking URL was adjusted, HubSpot will detect the discrepancy and redirect to the unsafe URL warning page, to protect you and your website visitors from mistakenly navigating to a spoofed version of your site.
To fix the issue, you can either:
- Re-embed the button CTA onto your website, without making any changes to the original embed code.
- Update the URL of the original button CTA to ensure the following two requirements:
- You own and manage the domain name in the URL.
- The
cta_guid
parameter is present, and has the value matching an active button CTA you own.
