I have recently installed Yoast and am generally pleased with the results. However, when Yoast is active my RSS feed from WP Events Manager that uses a query to exclude specific event category fails. As soon as I deactivate Yoast the RSS feed works again. The RSS feed that fails is as below: https://test.wiltshiretennis.org.uk/event/feed/?event-categories=-47 Removing the ? suffix as below works but includes all events: https://test.wiltshiretennis.org.uk/event/feed/ My site uses WP Rocket and Cloudflare and I have deactivated both of these and the problem persists. I have a basic Yoast setup with minimal changes. As the site uses Cloudflare, RSS validator and such won't work as these are seen as bots.
