Unfortunately, you sometimes have to cancel a planned event. In Events Manager it can be quite cumbersome to make sure you have done everything. This add-on makes that extremely easy!
Just change the Post Status to “Cancelled” and this add-on will automatically:
<ul>
<li>Close the Booking Form by adjusting the Event cut-off time to the timestamp of cancellation;</li>
<li>Change the Event Category to the new “Event Cancelled”;</li>
<li>Change the Booking Status to the new “Event Cancelled” for selected booking statuses;</li>
<li>Send the new “Event Cancelled” Email to notify your customers.</li>
<li>After cancelling an event, it will still be visible in the front end, but the booking form will be closed. This prevents 404-errors for visitors and search engines.</li>
<li>Refunding online payments remains a manual procedure.</li>
</ul>
This add-on is fully integrated with the Events Manager Dashboard. These new options will work exactly the same as the built-in ones.
<h3>Supports EM in Global Tables Mode</h3>
If you are running Events Manager on a WordPress MultiSite with Global Tables Mode enabled, you will probably have noticed that (by default) some features are missing on the sub-blogs. Unlike what the EM Dev told me, it is possible to filter the Admin Events List per Event Category if Global Tables Mode is enabled.
Since version 2.0 this add-on is (almost) fully compatible with that. The only thing still missing, is selecting Events Categories in the Quick Edit menu on sub blogs. But all other features of this add-on run smoothly.
Compatibility with <a href="https://wordpress.org/plugins/stonehenge-em-ongoing-events/" rel="ugc">EM – Ongoing Events</a>: 
If you cancel a main event, all sub events will be cancelled as well, but if you cancel a sub event, the rest of this Ongoing Series will remain unchanged.
<h4>How to test it?</h4>
Simply create a test event like any other. Publish it and add yourself as a participant. Then set the test event to “Cancelled” and watch the magic happen.
<h3>Feedback</h3>
I am open to your suggestions and feedback!

If you have check or transfer type orders for example, you will be able to set a maximum number of days or by hours to receive the payment.
Cancel Abandoned Order, will take care of checking this and change the status of the order to “Cancel” if you have not received payment on time.
