Error: There are unclosed HTML tags in the event details.
Last Updated: October 24, 2025
This means, the system is catching unclosed HTML tags in one of your event’s details section.
Fix 1: Go to Event > All Events in wp-admin and find this event, and check event main details HTML structure to make sure all html tags e.g., <div> <p> are closed properly e.g., </div></p>
Fix 2: Go to EventON Settings > Advanced Settings make sure Enable sanitizing HTML content for event data is unchecked.
