Hi Christy,
Thanks for reaching out on this! Sorry to hear you are experiencing this issue, I’ll try to help you getting this right soon.
… if I have it ending at a specific time on the last day (say 5pm), the event does not show up on the calendar for the last day.
Let me see if I understand this correctly: you create an event which start date and end date are not the same, and the event is not an all-day event. The event is not showing correctly on month-view, the last day is not there. Can you confirm this? I tried to re-create this on my end but it’s working fine, any additional steps/settings I’m missing?
A good starting point would be to confirm the following:
Have you made any customizations to the calendar? Can you confirm this is happening with no other plugins active and with default WP theme?
If the event starts and ends on the same day is this happening also? What about changing the end date to 1:00pm (or earlier) instead of 5:00pm, does it make any difference?
Please let me know about those and if it’s possible please provide a URL where I can see the site,
Thanks,
Nico
