HEllo, many thanks , yes with your guidance I Was able to find the issue issue was in the call to pll_rel_hreflang_attributes setting up the filter, which was not returning the array in some cases.

Regards

I investigated in much more detail, I see a comment in the my calendar code:

/**

• Customize canonical URL for My Calendar custom links
  */
  function mc_custom_canonical() {
  if ( mc_is_single_event() ) {
  add_action( ‘wp_head’, ‘mc_canonical’ );
  remove_action( ‘wp_head’, ‘rel_canonical’ );
  add_filter( ‘wpseo_canonical’, ‘mc_disable_yoast_canonical’ );
  }
  }

/**

• When Yoast is enabled with canonical URLs, it returns an invalid URL for single events. Disable on single events.
  *
• @return boolean
  */
  function mc_disable_yoast_canonical() {
  return false;
  }

I am not really sure about this. Both the yoast and myCalendar canonical seem to returning the ?mc_id, this is incorrect. It is easy for me to filter this, but the yoast filter is disabled, is there another hook I can use?

just a quick follow up, I see that when the event list are generated, the links in the event also have the query ?mc_id=xxx , so infact they point to the page which is not in the sitemap. when I manually remove the ?mc_id=xx it works. So is it possible to generate the links without the query?

Hello again, seems like I have to set the language individually for all pages. The answer for my question is here:
https://polylang.pro/doc/assign-a-language-to-an-existing-content/

I close this topic. Perhaps the above link can be added to your FAQ to cover cases such as mine where polylang is added to a site which already has many pages.

thanks again, actually I think I found the culprit elsewhere.

M y themese has a call to wp_head()
and I needed to remove the canonical being generated there as suggested on stackoverflow:
