Thanks for reaching out @mariagammelbys. Based on what you’re describing, some of the records for your site on the Site Kit service may be invalid, referencing your staging site. To try and resolve this, please follow the steps below:

1. Visit your site settings (Settings > General).
2. Change your site address (URL) and WordPress address (URL) from https://gammelbys.dk to https://www.gammelbys.dk
3. Press the save button.
4. Attempt Site Kit setup once more after logging back into your site.

Let me know how you get on with the above. Note that we can revert back to the original site URLs afterwards should you be able to proceed. This change can trigger Site Kit to request new site records for your live site, with the new URL.

If the same occurs, let me know of the following:

1. Your Site Health information. You can use this form to share privately if preferred.??
2. Is the staging site on the same staging site URL as it was previously? I ask as we may need to perform some actions within Site Kit to ensure any invalid records on your live site are removed.
3. Are you performing regular pushed from your stating site to your live site? I ask as this can cause issues if you have Site Kit setup on your staging site.

Let me know if you have any questions with the above.

I’m just following up with you to check whether you’ve had an opportunity to perform the above? If so please share whether you were since able to set up Site Kit successfully.

As we didn’t receive a response I’ll mark this as resolved. Feel free to open a new support topic if you continue to encounter issues, or reopen this topic and we’d be happy to assist.
