Old topics published via WordPress embed are missing x-robots: noindex and canonical tags

Hey Thiago,

Just so I understand, are you saying the following:

  1. You have the site setting Embed set canonical URL enabled, and have always had it enabled.
  2. You have multiple topics published from your Wordpress to your Discourse via the Wordpress Discourse Plugin over a period of some time.
  3. Up until recently, all of the Discourse topics published as described in 2 all had a a link rel="canonical" with the href set to the wordpress url in their head.
  4. At some point recently, you think some subset of those topics which previously conformed to 3 now have a link rel="canonical" with the href set to the Discourse url.

Is that correct?
