Would like to show participants

I haven’t used the plugin before, but couldn’t you add the following placeholders to your (single) event template? https://wp-events-plugin.com/documentation/placeholders/#

Thank you for help. Its sholuld be #_ATTENDEESLIST for the event template. But i can not find the place where i have to put ot in.

Best wishes

Try within your page content itself (follow the examples at the bottom of the page). Otherwise, you will need to edit the template that is found within plugin_dir/templates/templates/event-single.php. Please refer to the documentation on perhaps adding this to your child theme (if you have one) otherwise the changes will be lost on plugin update.
