If you have set up your event using one theme and then activate a different theme, it will not be automatically applied any existing events. This is because if you choose to select a different default theme for your account, you wouldn't necessarily want all existing events to have the new default theme automatically applied.

To apply the new template from the new theme to an existing event, follow these quick steps.

1. Select the event and then click Edit Details in the event screen.

2. Then scroll to the bottom of the window and click Save Details.

The template will now be live on the existing event.
