Your property pages show a 404 error while the rest of your site loads normally. Your content is still there.
Why this happens. This is a WordPress permalink (rewrite rules) issue. It often happens after a plugin update.
How to fix it. Saving your permalink settings rebuilds the URL rules.
- In your WordPress admin, go to Settings > Permalinks.
- Click Save Changes once without changing anything.
- Reload a property page. It should resolve again.
If the 404 errors return after a later plugin update, repeat the same step. If they keep coming back on their own, contact support so the underlying cause can be tracked down.
