If you see this error when connecting your WordPress site to Kintsu AI, your site’s permalink settings may need to be updated.

​
How to fix

1

Open permalink settings

In your WordPress admin, go to Settings → Permalinks.
2

Change the permalink structure

Select any option other than “Plain” (we recommend Post name).
3

Save your changes

Click Save Changes.
4

Reconnect to Kintsu AI

Go back to Kintsu AI and try connecting again.

​
Why this happens

Kintsu AI communicates with your WordPress site through its REST API. This API requires “pretty permalinks” to be enabled — which is any permalink setting other than “Plain.” Most WordPress sites have this enabled by default, but some hosting environments or fresh installations may use the “Plain” option.

​
Still not working?

If you’ve changed your permalinks and are still seeing this error, it could be caused by:
  • A security plugin (like Wordfence or Sucuri) blocking API requests
  • A firewall (like Cloudflare) challenging bot traffic
  • Your hosting provider blocking external API access
