Hey Thiago,
Just so I understand, are you saying the following:
- You have the site setting
Embed set canonical URLenabled, and have always had it enabled. - You have multiple topics published from your Wordpress to your Discourse via the Wordpress Discourse Plugin over a period of some time.
- Up until recently, all of the Discourse topics published as described in
2all had a alink rel="canonical"with thehrefset to the wordpress url in theirhead. - At some point recently, you think some subset of those topics which previously conformed to
3now have alink rel="canonical"with thehrefset to the Discourse url.
Is that correct?
