Could you share the site you’re seeing this on, and if you know it, which page or link is causing this error to be generated? * Thread Starter [creativechaos](https://wordpress.org/support/users/creativechaos/) * (@creativechaos) * [1 year, 6 months ago](https://wordpress.org/support/topic/wordpress-database-error-column-link_id-cannot-be-null/#post-18128069) * I can’t tell which page is causing the error. It seems very sporadic… it has happened 6 times over the past 24 hours. The website is fytogreen.com.au * I’ve tried triggering the error by viewing pages across the site, and then looking at the error_log file to see if it’s logged a new entry but I can’t figure out how it’s being triggered. * [mairag](https://wordpress.org/support/users/mairag/) * (@mairag) * [1 year, 6 months ago](https://wordpress.org/support/topic/wordpress-database-error-column-link_id-cannot-be-null/#post-18135361) * I’m having the same error in the log, a lot of lines like this one actually: [ 15-Oct-2024 22:30:49 UTC] WordPress database error Column ‘link_id’ cannot be null for query INSERT INTO `wp7c_track_the_click_hit` (`link_id`) VALUES (NULL) made by require(‘wp-blog-header.php’), wp, WP->main, WP->parse_request, do_action_ref_array(‘ parse_request’), WP_Hook->do_action, WP_Hook->apply_filters, rest_api_loaded, WP_REST_Server->serve_request, WP_REST_Server->dispatch, WP_REST_Server->respond_to_request, Track_The_Click_Public->track_click_v2 * Thread Starter [creativechaos](https://wordpress.org/support/users/creativechaos/) * (@creativechaos) * [1 year, 3 months ago](https://wordpress.org/support/topic/wordpress-database-error-column-link_id-cannot-be-null/#post-18297733) * We are still seeing this error in our server logs. eg.
