Any ideas what this could be?
Duplicate entry '0-366545fb3ba9b75-0-0' for key 'unique_tracking' for query INSERT INTO `wp_wpforo_visits` (`ip`, `time`, `topicid`, `forumid`) VALUES( '366545fb3ba9b75', '1575912156', 0, 0 ) made by require('wp-blog-header.php'), require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), do_action('wp_loaded'), WP_Hook->do_action, WP_Hook->apply_filters, wpforo_logs, wpForoLogs->visit, wpForoLogs->add_visit
I see that i'm again plagued with the same old problem.
Shall i ignore it?
You can ignore this error for sure. This is a rare single case. The core function is made to avoid duplication. This duplication was based on 0 values of topic and forum IDs. This is a causal case.
