Pending release


We have an article in our knowledgebase where we provide a snippet to mark certain fields on the Community Event submission form as required. Currently marking the organizer field as required will not have any affect. This will be fixed in the next release.

Your update failed due to an incompatibility …

Note: Info


When running an update on the calendar / ticketing plugins the update might fail and you might receive a message like this:

Your update failed due to an incompatibility between the version (5.1.0) of the The Events Calendar you tried to update to and the version of The Events Calendar PRO that you are using. Read More.

This is a feature implemented in our plugins. If you are using several of our plugins, then during the update process it will be checked whether the versions you want to and can update to are compatible with each other or not.

For example your Events Calendar Pro license has expired last month. A new release for The Events Calendar and Events Calendar Pro just came out and you would like to update. However, you cannot update Events Calendar Pro – due to the expired license – and updating The Events Calendar would cause an incompatibility and might crash your site. The system recognizes this and will not allow the update of The Events Calendar to keep your calendar working and you will be presented the above message.

The solution:

  • Make sure that you have access to the needed versions of all the plugins.

Shared Capacity ticket showing as sold out and other ticket capacity issues

Fixed in ET 4.11.5 / ET+ 4.11.4

Description: If tickets are set up with shared capacity, they will show up as zero available on the back-end and as sold-out on the front-end. We are currently investigating the different scenarios where this happens.

If you are experiencing the same issue and you are opening a support ticket, please include these details as well to speed up the process:

  • Are you using the classic editor or the block editor for events?
  • Are you using any of the Classic Editor or Disable Gutenberg plugins?
  • What plugin versions are you using?
  • Are you using legacy / V1 views or the new / V2 views?
  • What Attendee Registration setting do you use? Default, Modal or Shortcode?
  • What payment gateway are you using for ticket sales?
  • Sharing your system information is also super helpful.

Additionally, these questions also help us reproduce the issue you are experiencing:

  • Did you create tickets with shared capacity, publish, and later manually edit? Please clarify.
  • Are you moving an attendees ticket to another event ticket or within tickets of the same event?

Affected Plugins:

  • Event Tickets Plus 4.11.2+

Possible Workaround:

  • Set up the first ticket with single ticket capacity and save it. Then edit and change to shared capacity before adding any other tickets. Note: this might not work in all cases.


  • A fix has been developed and is under testing. If all goes well it will be published by the end of March. (Targeting March 18.)

Wrong time / time zone is shown for events after WP5.3 update

Note: Info

Description: After updating to WordPress 5.3, the time and / or the time zone of the events is wrong. In most cases the time is shown in the UTC time zone.

This is caused by the date_default_timezone_set function, which should not be used any more. See the ‘Not recommended’ section in this post.

Update: As of Events Calendar PRO 4.7.10 we are no longer using the date_default_timezone_set function.

Solution: If you are still experiencing glitches with the time or time zone of the events, please read this post for further information and a solution.

QR code scanner does not recognize API key

Note: Info

Description: When scanning a valid QR code of a ticket, an error message similar to the below appears on the screen:

  • “Please Verify API Key is Correctly Entered on the Settings Page”

In some cases the server configuration is not allowing the URL (that is coming from the QR code) to go through properly. The URL should be returning a JSON response, but it instead looks to be redirecting to a HTML page. Please contact your hosting provider to investigate this.

In case server configuration is right and confirmed by the hosting provider, then create a support ticket with the following information:

  • Set up a test event in the future and share the URL
  • Set up a ticket for the event that our support team can ‘purchase’ for free, so we can receive a QR code to scan
  • Share with us the API key for the app

To find out more about the error messages in the Event Tickets Plus App please check out this post.
