It was a simple error on the type of page… It was not the PHP function is_page(), but is_archive().
It’s resolved.
Hi bsil & Mikegraf,
I encounter the same problem on my website, but it seems to be a bug which not affect your real URL. The bug only concerned the Yoast box, but if we have the same bug, your canonical URL is the same as your permalink. Just check it in the Google Chrome console when you visit your website.
Let me know your feedbacks 🙂
Hi, I have the same problem here on my website…
Do you have any solution for the moment ? We have to do all post URL manually?
Thanks in advance!
