Search box does not work

Hi,

I am using the latest events calendar plugin v 6.2.9. In the /events page there is a search box, when type something in it then click on ‘find events’ nothing appear.

The error log:

PHP message: WordPress database error Unknown column 'wp_tec_occurrences.start_date' in 'field list' for query SELECT   wp_posts.ID, CAST( wp_tec_occurrences.start_date AS DATETIME ) AS event_date, CAST( wp_tec_occurrences.duration AS DECIMAL ) AS event_durationFROM wp_posts  INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )WHERE 1=1  AND (((wp_posts.post_title LIKE '%voluntary%') OR (wp_posts.post_excerpt LIKE '%voluntary%') OR (wp_posts.post_content LIKE '%voluntary%')))  AND (wp_posts.post_password = '')  AND (   ( wp_postmeta.meta_key = '_EventEndDate' AND CAST(wp_postmeta.meta_value AS DATETIME) > '2023-12-18 13:28:09' )) AND wp_posts.post_type IN ('ai1ec_event', 'post', 'roundtable', 'sponsoredcontent', 'sponsored_content', 'video_posts', 'job_listing') AND ((wp_posts.post_status = 'publish'))GROUP BY wp_tec_occurrences.occurrence_idORDER BY event_date ASC, event_duration ASC, wp_posts.post_title LIKE '%voluntary%' DESC, wp_posts.post_date ASCLIMIT 0, 13made by WP_Query::get_posts

But when I exported the sql files, there actually have table wp_tec_occurrences, and the start_date column is there too.

The website is under a wordpress network site. Any idea?
