Empty Short code

I guess your event start date and end date settings are not correct. I request you to please open all your events in edit mode and check the Date settings tab.

Thank you Abdhulla,
Yes, I’m rechecking those and those are in the right format.
I’m adding those screenshots below.

Test event https://virtuallivetraining.com/training-events/test/

And I found the problem in the plugin.
I Purchased the recurring event plugin and added 12 dates of all months.
Where ill enter the first date of Feb and so on with march to Dec.
The event is not showing after the date in Feb passed.
It supposes to show the event and it only hides the passed date and should show the rest of all dates in the same event. this was right before the update and it’s making me the big problem now.

If I add the Dec Even in the first then it will show everywhere as it’s a Dec Event.

Please check also one more this, I guess there is an issue, Go to

Event Settings -> General Settings -> Event Expire On

Then select the Event End Date and save the settings. I guess this setting is currently set as Event Start date so when the start passed event not showing in in the front-end.

Please let me know the update.
