Already put information for Site Kit by Google | Site Health Information.
Thanks for reaching out, and sharing your Site Health information @willuuu. Based on the checks I’ve been performing on your site, I suspect Site Kit may be making use of a no longer valid callback. I saw this as I can see you’re using a custom directory added to your login URL. To ensure you can connect, please share the following:
- Do you recall having set up Site Kit successfully on this site previously? If so, did you have a standard wp-admin path without making use of WordPress in it’s own directory? If so let me know what changes you may have made.
- What is the URL you land back on when attempting setup? I ask as this may contain a no longer valid callback URL, based on your previous site. I’m aware it’s an edit.php file, although there may also some Site Kit references added to the URL.
- What is your current location? I ask as Google Services may be restricted in some regions.
Let me know if you have any questions with the above.
Thanks for your reply, @jamesosborne. I discovered that the issue was with the theme. After activating a different theme, I successfully connected Site Kit. Thank you!
