I have the solution, in the file nxs_functions_engine.php in the line 151, it’s the problem:
$ttr = "FROM ". $wpdb->prefix . "nxs_query WHERE timetorun<'".date_i18n('Y-m-d H:i:s')."'"; $quPostsCnt = $wpdb->get_var($wpdb->prepare("SELECT COUNT(id) %s", $ttr));*
change the code to this:
$ttr = $wpdb->prefix . "nxs_query WHERE timetorun < %s"; $current_time = date_i18n('Y-m-d H:i:s'); $query = $wpdb->prepare("SELECT COUNT(id) FROM $ttr", $current_time);
$quPostsCnt = $wpdb->get_var($query);
If you have problems with the query/timeline and log/history, the problems are other queries, cheers!
