Hello Sebastien,
Thanks for getting in touch and for checking out The Events Calendar!
I have seen compatibility issues reported between Divi and The Events Calendar in the past but most of those have either been resolved or cleared up in recent versions of the theme and the plugin. There may still be some issues, but we find that many people using them together experience no issues at all.
That said, it sounds like the issue you’re describing might be related to appearance and could be resolved with CSS. For example, are you able to target the navigation on the events page and move it accordingly to ensure it is not blocking content on the page? Here’s an article on how to use DevTools to search for calendar styles in CSS. Our Themer’s Guide also walks through some tips on how to customize the calendar’s styles to achieve an appearance that fits better with your theme.
Does this help answer your question? Please let me know. 🙂
Cheers,
Geoff
