Hi there,
This seems to be an issue related to The Events Calendar plugin. This forum is for the Event Tickets plugin. I would recommend posting your question over there for best results. https://ww.wp.xz.cn/support/plugin/the-events-calendar/
I will say that I searched our plugins for where we are doing things with “no index”, and I was only able to find one place. There is a filter there with the following note added:
Runs on the “wp” action. Inspects the main query object and if it relates to an events query makes a decision to add a noindex meta tag based on whether events were returned in the query results or not. Disabling this behaviour always is possible with: add_filter( 'tribe_events_add_no_index_meta', '__return_false' );
Try adding that snippet to your child theme’s functions.php, and see if that helps with the pages you are looking at.
Best,
Sky
