Good evening Phil and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the page turning blank.
I would love to help you with this topic.
I would recommend the following:
- Head over to Events -> Settings -> Community and hit “Save Changes”
- Head over to WP-Admin > Settings > Permalinks and re-save the permalinks
- Try temporarily reverting back to a default WordPress theme such as twenty-sixteen to se if that helps
If that still does not work, after a quick backup of your plugins and database, please update all of our plugins to their latest version.
Let me know how that goes.
Best regards,
Geoff B.
