Hi Carly Petersen -- thanks for reaching out, sorry to hear there is something go wrong. A few quick troubleshooting items...
- Ensure you are creating events for an initiative with a site (doesn't matter the sharing visibility)
- Make sure all required fields are correctly filled out
You'd be surprised how often those two things solve issues. If not, which sounds like might be your case, then try and save an event as a draft (only the title is required) and making updates to the event you already creating (could be as small as a quick punctuation change).
If any of those fail and you still cannot create new events, then shoot me an email @ brollison@esri.com so we can troubleshoot your org's events system. Thanks!
