Good evening Geoff and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
What is going on is that Divi is limiting the number of posts allowed from your archives.
You can either:
- Change that setting directly in Divi
- Install and use the following extension: https://theeventscalendar.com/extensions/elegant-themes-divi-theme-compatibility/
As for the blank page, I would look at your caching plugin’s settings.
Finally, as a side note, it looks like you are not using the very latest version of our Filter Bar plugin. You might want to upgrade that as well.
Let me know how that goes.
Best regards,
Geoff B.
