Hi @lortan29,
Thank you for reaching out.
We see that your WordPress site is configured with the WWW and the non-WWW version is redirected to the WWW version. The canonicals Yoast outputs are based on the Site URL under Settings → General. We see that thecanonicals are showing the WWW version and that is expected in this scenario.
Hi @lortan29,
Thank you for your reply. We can confirm we see the canonical there without the WWW. Have you recently changed this?
Can you please try to do the following:
1) Install the Yoast Test Helper plugin, found here https://ww.wp.xz.cn/plugins/yoast-test-helper/
2) Go to Tools → Yoast Test
3) Click the Reset Indexables tables & migrations button.
4) Go to SEO → Tools.
5) Click the Start processing and speed up your site now button and let it complete.
This should take care of the canonicals.
Awesome, thank you for letting us know. 🙂
