Good evening Kimberly and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the Events slug returning a 404 error message.
I would love to help you with this topic.
Please try the following:
- Re-save your setting under Events -> Settings -> General
- Make sure that your default view’s checkbox is checked under Events -> Settings -> Display
- Make sure you have no “real page” that shares the same slug as the Events URL slug page (the calendar is not a real page and needs exclusivity of that slug)
- Re-save your permalinks.
Let me know how that goes.
Best regards,
Geoff B.
