Hi there Karlijn,
Thanks for getting in touch with us! I’ll help you here 🙂
First of all, Can you please follow the steps described in our Testing for conflicts guide? This way we can see if this is a problem in our plugin or a conflict with the theme or other installed plugins.
If the problem persists can you please give me more details about the events not showing in the site? Are those recurring events, all day events or have any settings in common that other events don’t have? Also, how are events ordered on the site? Was this working differently in the past?
Best,
Nico
