I have NO idea when the call is happening, but it’s happening for event pages. Nothing ever loads – the database call starts while my browser spinner is still going slow and nothing is showing on the screen – so I suppose it’s pretty early in the page load.
You can get a link to the database dump at https://1ty.me/hAEoK5Eo6 – that’s a one-time link that will show you where to download a dump of the wp_posts and wp_postmeta tables. (If you want/need other tables, please let me know. I didn’t dump the whole database because there are non-WP things in there that I’d prefer not to share. 🙂 Please let me know if that doesn’t work for you.
Thanks for the offer of assistance!
