I saw a post related to Jetpack for a similar problem (though it seems to be in the back-end) but I do not have Jetpack enabled on my site.
Since the upgrade to 4.8.21 this is a screenshot of my single event page (no tickets selection available):
Are there any custom templates for your single event page in your WordPress theme?
It will help to know the name of the theme, or where we can get a copy of the theme so we can rule out whether or not it’s a theme issue. The new version of Event Espresso 4 adds a feature where you can re-arrange the content of the single event page, but your theme (or another plugin) may not be ready for that.
If the event content loads correctly with single.php, you can add the custom date display to single.php and wrap the date display in a conditional check.
The support post ‘Upgrading to 4.8.21 messed up the front-end single event page’ is closed to new replies.
